Chem question? 2. A block of material has a volume of 2 m3. It has a mass of 1 * 104 kg. Calculate the density of the material sample and express your results in g/cm3 with appropriate scientific notation.

The density (d) is the quotient when mass (m) is divided by the volume (v). It is specified that the densities be in units of g/cm³. So, there is a need to convert first the given mass and volume to proper units. The calculations are shown below,

2 m³ x (100 cm / 1 m) ³ = 2.0x10^6 cm³

1x10^4 kg x (1000 g / 1 kg) = 1.0x10^7 g

Calculating for density,

d = m/v = (1.0x10^7 g) / (2.0x10^6 cm³) = 5 g/cm³
