How do you calculate rock density?

How do you calculate rock density?

Divide the mass of the rock by its volume to calculate the density of the rock. In our example, the density is 20.4/8 = 2.55 g/cubic cm. Divide the rock density by the density of water to calculate the specific gravity.

What are the 3 density formulas?

What are the three formulas for density?

  • To work out density: p = m / V.
  • To work out the mass: m = p x V.
  • To work out the volume: V = m / p.

How do you calculate volume of a rock?

Multiply the length, width, and height together to find the volume of the space. Now, convert the volume to cubic yards. If the initial measurements were in inches, then convert cubic inches to cubic yards by dividing by 46,656. If the initial measurements were in feet, then divide by 27 to get cubic yards.

What is the density of a rock?

Density is a measure of the mass of a substance per unit measure. 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….Rock Densities.

Rock Density
Rock salt 2.5–2.6
Sandstone 2.2–2.8
Shale 2.4–2.8
Slate 2.7–2.8

What is the density of a small rock?

For example, sandstone (characteristically quartzose) has a typical dry bulk density of 2.0–2.6 g/cm3, with a porosity that can vary from low to more than 30 percent. The density of quartz itself is 2.65 g/cm3….Density of Rocks and Soils.

Soil Type Density/g/cm3
shale 2.06–2.67
slate 2.72–2.84
pyrite 5.0
gold 19.3

What is the density of a rock which has a mass of 35 grams and a volume of 7.0 cubic centimeters?

5.0 g/cm3… Get solutionsGet solutions Get solutions done loading Looking for the textbook? What is the density of a rock with a mass of 35 grams and a volume of 7.0 cubic centimeters? The density is defined as the specific amount of mass per unit volume of a substance.

What is density formula and units?

Kilogram per cubic meter
Density/SI units

How do you find density with Grams and mL?

The density (d) of a material is its mass (m) divided by its volume (V). Calculate the density of an object that has a mass of 25.0g and the volume is 10.5ml. Calculate the mass of an object that has a density of 8.92 g/ml and the volume is 5.25 ml….

vol= 21.0g
12.0g/ml

What is the density of stone?

Density of Some Common Building Materials

Material Density
Crushed Stone 100 lb/ft3 1,600 kg/m3
Earth, loam dry excavated 90 lb/ft3 1,440 kg/m3
Earth, packed 95 lb/ft3 1,520 kg/m3
Glass, window 161 lb/ft3 2580 kg/m3

What is the densest rock?

Two of the heaviest or densest rocks are peridotite or gabbro. They each have a density of between 3.0 to 3.4 grams per cubic centimeter. Interestingly, peridotite are the rocks that naturally occurring diamonds are found in.

What is the formula for volume of a rock?

If you don’t have a measuring beaker or water available, you can still estimate the volume of the rock. If you assume that the rock is a perfect sphere, you can measure the diameter of the rock and use the formula: V = 4/3 π_r_³ with V the volume and r the radius (or half the diameter) of that sphere.

How do you calculate volume of rock?

In our example, the rock volume is 63 – 55 or 8 ml. Divide the mass of the rock by its volume to calculate the density of the rock. In our example, the density is 20.4/8 = 2.55 g/cubic cm.

How to figure the amount of pea gravel needed?

How to Figure the Amount of Pea Gravel Needed. If the area to be covered is a square or rectangle, you easily can calculate the amount of pea gravel needed by hand. Measure the length, width and depth in feet of the area to be covered. Multiply the three numbers together. Divide by 27 to get the number of cubic yards of pea gravel needed.

How do you calculate yards of gravel?

To determine the cubic yards of gravel you’ll need, first convert all measurements to yards if they’re in inches, feet or another unit of measure. Then, multiply your length by the width by the depth of gravel. This number is the cubic area.
