If the relative density of gold is 19.2, the volume of 2.4kg of gold is?
8.00 x 10-3 m3
1.25 x 10-4 m3
1.92 x 10-4 m3
4.61 x 10-3 m3

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
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
