Question

a cork piece weighs 6.5 gf in air .To determine its relative density, a lead sinker of weight 43 gf is used. The cork and sinker together weighs 11.5 gf in water. If the relative density of lead is 11 ,then find(a) loss of weight of the sinker when immersed in water,(b) weight of the cork in water, (c) loss in weight of the cork, and (d) relative density of cork.
Answer in step by step ​

Answer 1

EXAMPLE 7.7. A piece of cork weighs 6.5 gf in air. To find its relative density, a lead sinker of weight 43 gf is used. The cork and the sinker together weigh 11.5 gf in water. If the relative density of lead is 11.0, find loss in weight of sinker when immersed in water
