Question

A substance has a mass of 20 kg and volume of 40 m3. The specific gravity of the substance is 0.80 kg/cm3. What is the reference density (Kg/m3)?

(a) 0.25

(b) 0.50

(c) 0.75

(d) 1.00

Answer 1

Correct choice is (a) 0.25

The explanation: Specific gravity = density of the substance / Reference density.
