|
27 g/cm3

39 g/cm3

Detailed explanation-1: -To calculate the density, divide the weight by the volume: 9 g / 37.5 cm3 = 0.24 g/cm3 = 240 kg/m3.
Detailed explanation-2: -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.
Detailed explanation-3: -Problem 2: You have a different rock with a volume of 30cm3 and a mass of 60g. What is its density? Density is mass divided by volume, so that the density is 60 g divided by 30cm3, which is 2.0 g/cm3.
Detailed explanation-4: -Look up the density of the material the object is made of in kg/m3. Measure the mass (or weight) of the object in kilograms. Divide the mass by the density. You will then have the volume of the object in m3. 21-Dec-2022
