Question

piece of steel has a volume of 5 cm3 and a mass of 40 g. What is its density in (a) g / cm3 (b) Kg / m3 ? 2. What is the mass of air in a room measuring 10.0 m X 5.2 m X 2.5 m, If the density of air is 1.3 Kg / m3 ?​

Answer 1

Answer:

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. For example, the density of water is 1 gram per cubic centimetre, and Earth's density is 5.51 grams per cubic centimetre.
