The mass of an object is 100 g and its volume is 500 cm^3. What is the object's density in units of kg / m^3

The density of th object in units of kg / m^3 is 200 kg/m³

Explanation:

Density = mass/volume

However, to solve this, we first convert the units from grams to kkilograms and from cm³ to m³ thus

1 g = 0.001 kg therefore 100 g = 100 * 0.001 kg or 0.1 kg

also 1 cm³ = 0.000001 m³ therefore 500 cm³ = 0.0005 m³

From this, we can now find th density as

0.1 kg/0.0005 m³ = 200 kg/m³
