How do you express density as a decimal?

Answer 1

density equals mass over volume, so divide the mass by the volume. Example: 100 grams in 30 liters= 100/30=3.3 g/L ALWAYS include a unit!

Answer 2

Density is typically expressed in units of mass per unit volume, such as grams per cubic centimeter or kilograms per liter. To convert this to a decimal, simply divide the mass by the volume. For example, if the mass is 50 grams and the volume is 25 cubic centimeters, the density would be 50/25 = 2 grams per cubic centimeter, which can be written as 2.0 g/cm^3.
