Question

A solid weighs 32 g in air and 28.8 g in water. Find how much will it weigh in a liquid of relative density 0.9.

• A. 29.00
• B. 29.12
• C. 30.08
• D. 32.14

Answer 1

The correct option is B

29.12

Relative Density of liquid = Loss of weight in liquid/ Loss of weight in water
$0.9=\frac{x}{32}-28.8$
$0.9\times 3.2=x$
$x=2.88$
Weight of solid in liquid = 32 - 2.88 = 29.12 g
