Question

A cork weighs 8 gf in air. When tied to a sinker, the combination is found to weigh 34 gf in water. If the sinker weighs 38 gf in water, find the relative density of air.

Answer 1

Explanation:

Step 1: Given data,

Weight of cork in air =

Weight of cork and sinker in water =

Weight of sinker alone in the water =

Step 2: Finding the weight of cork in water,

Step 3: Finding relative density (RD) of the cork,

Hence, the relative density of the cork is 0.333
