## What is the ratio of the mass of a substance to the mass of an equal volume of water?

The “Specific Gravity” of a substance is the ratio of its mass to that of an equal volume of water at the same temperature and pressure. This is also the ratio of the densities of the two substances: SG = (mass of a volume V of a material)/(mass of a volume V of water) = (rMaterial/rWater).

## How can we identify a mineral just by knowing its mass and volume?

You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. You can determine the volume by dropping the object into a graduated cylinder containing a known volume of water and measuring the new volume.

## How are minerals measured?

The Mohs Hardness Scale is the main scale to measure mineral hardness. Finger nail is 2.5, copper coin is 3.5, glass is 5.5 and steel is 6.5. Hardness scale is Talc is 1, Gypsum is 2, Calcite is 3, Fluorite is 4, Apatite is 5, Orthoclase Feldspar is 6, Quartz is 7, Topaz is 8, Corundum is 9 and Diamond is 10.

## What is the density of the mineral?

Density is an intrinsic physical property of minerals that relates to the composition of the mineral and to the pattern in which the mineral’s atoms are arranged. “Intrinsic” means that the property is the same for the mineral, no matter what the size or shape of the sample.

## What are the two ways to write density formula?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre./span>

## Which mineral has the highest density?

For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier….Mineral Densities.

Mineral | Density |
---|---|

Calcite | 2.71 |

Chlorite | 2.6–3.3 |

Copper | 8.9 |

Feldspar | 2.55–2.76 |

## Which mineral in the table is the hardest?

diamond

## What is the heaviest rock on Earth?

peridotite

## What is the densest rock on Earth?

## What is the lightest rock in the world?

pumice

## What is the heaviest metal?

Osmium

## Is rock heavier than water?

Ninety-nine percent of all rocks on earth are denser than water at ambient temperatures (the water is liquid) and therefore those rocks will sink in water. One rock type is lighter (due to trapped air bubbles) and will float. This rock is a volcanic (extrusive) rock known as ‘pumice’.

## What weighs more water or gravel?

If so, then it’s heavier than water. Most gravel has a specific gravity of 2.400 to 2.600 (with water = 1.000), so most typical gravels weigh 2.4 to 2.6 times more than water at a given volume./span>

## How heavy is a 5 gallon bucket of rocks?

about 70 pounds

## What is heavier rocks or sand?

A small rock would obviously weigh less than a roomful of soil, but rock is heavier in the sense that a rock of given size weighs more than the same-size sample of soil. Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below)./span>

## What is heavy water or sand?

Sand is heavier than water when the volume of both substances is equal. The density of dry sand is between 80 and 100 pounds per cubic foot, whereas water is 62 pounds per cubic foot. The density of water depends on its temperature.

## Is sand heavier than gravel?

per given volume sand is going to weigh more as you can fit move in a given volume the pore space between sand grains is smaller than the pore space between gravel article. According to Glover lose dry gravel weighs about 1522 kg per cubic meter. dry sand weighs about 1602 kg per cubic meter.

## What is the volume of a rock?

To find the volume of the rock, subtract the initial volume of the water from the final volume of the water: 50 mL – 30 mL = 20 mL. Therefore, the volume of the rock would be equal to 20 mL or 20 cc.

## How do I find the volume?

To find the volume, you multiply length times width times height, which is 3x1x2, which equals six.

## What is the best way to measure the volume of a piece of rock?

To find the volume of a rectangular object, measure the length, width and height. Multiply the length times the width and multiply the result by the height. The result is the volume. Give the result in cubic units, such as cubic centimeters.

## What is formula for mass?

One can consider the mass of an object as a measure of how much physical “stuff” makes up that object. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume./span>

## What is the volume of the square pyramid?

Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid: V = (1/3)a2h.

## How do you find out the volume of a shape?

Volume is the amount of space a 3D shape takes up. This is written as 1 cm³. You can work out the volume of a shape by multiplying height × width × depth.

## How do you solve surface area and volume problems easily?

Tricks to solve Volume and Surface Area Problems

- CUBOID. Let length = l, breadth = b and height = h units. Then.
- CUBE. Let each edge of a cube be of length a. Then,
- CYLINDER. Let radius of base = r and Height (or length) = h. Then,
- CONE. Let radius of base = r and Height = h. Then,
- SPHERE. Let the radius of the sphere be r.
- HEMISPHERE. Let the radius of a hemisphere be r.

## How do we calculate the volume of a prism?

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

## How do you find the volume of a 3D shape?

3D shapes have volume: the amount of cubic space inside of them. To find volume, you basically need the three dimensions: length, width, and height. For prisms, the formulas are derived by taking the area of the shape at the end, and multiplying that times the figure’s height.
