Question

A block of material has a volume of 2m^3. It has a mass of 1 ×10^4 kg. Calculate the density of the material sample and express your results in g/cm^3 with appropriate scientific notation.

Answer 1

Answer:

The answer to your question is: density = 5 g/cm³

Explanation:

Data

Volume = v = 2 m³

mass = m = 1 x 10⁴ kg

Density = d = ? g/cm³

Formula

density = mass/volume

Volume

                          1 m³ -------------------  1 000 000 cm³

                          2 m³ ------------------     x

                          x = (2 x 1 000 000) / 1

                         x = 2 000 000 cm³

Mass

                          1 kg ------------------   1000 g

                         1 x 10⁴ kg ------------    x

                         x = (1 x 10⁴ x 1000) / 1

                         x = 10 000 000 g

density = (10 000 000) / 2 000 000

density = 5 g/cm³
