Question

The density of mercury is 13.6 g cm -3 . Express it in kg m -3

Answer 1

Answer:

13.6 g/cm³ = 13600 kg/m³

Explanation:

1g = 10⁻³ kg

1cm³ = 10⁻⁶ m³

Hence,

1 g/cm³ = 10⁻³ / 10⁻⁶ kg/m³

1 g/cm³ = 10⁻³⁺⁶

1 g/cm³ = 10³ kg/m³

Therefore,

13.6 g/cm³ = 13.6 * 10³ kg/m³

                  = 13600 kg/m³
