If the relative density of gold is 19.2; the volume of 2.4kg of gold is?

A. 8.00 x 10^-3 m³
B. 1.25 x 10^-4 m³
C. 1.92 x 10^-4 m³
D. 4.61 x 10^-3 m³

Correct Answer:

Option B = 1.25 x 10^-4 m³

Explanation

R.D = (density of the subs)/density of water
19.2 =(P)/103; ∴P = 19.2 X 10³
But Vol. = (Mass)/density = (2.4)/19.2 x 10³
= 1.25 x 10^-4 m³
