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
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
