Study Notes

Density Calculations

Density is the mass of a substance divided by its volume.
Formula: Density = Mass / Volume.

Examples of Density Calculations

A 2.75 g sample in 250.0 mL yields a density of 0.011 g/mL.
The density of silver (Ag) is 10.5 g/mL; for a volume of 965 mL, mass equals 10,132 g.
Carbon tetrachloride (density of 1.60 g/mL) has a volume of 22 mL for 35.2 g of mass.
Ethanol has a density of 0.789 g/mL; a volume of 150.0 mL corresponds to a mass of 118.35 g.
A gold sample occupies 9.5 mL with a mass of 71.9 g, resulting in a density of 7.57 g/mL.
A ring with a mass of 4.53 g and volume of 0.212 cm³ has a density of 21.4 g/cm³.

Definitions and Concepts

Volume refers to the amount of space an object occupies.
Mass is the quantity of matter in an object.
The volume of a solid can be calculated as Length x Width x Height.

Important Formulas

Volume can be derived using the formula: Volume = Mass / Density.
Mass can be calculated with the formula: Mass = Volume x Density.
