A piece of marble tile weighs 100g in air. if it's density is 2.5g/cc,

1.	A piece of marble tile weighs 100g in air. if it's density is 2.5g/cc, what will be its weight in water
Answer» EXPLANATION:VOLUME of MARBLE = 100/2.5 = 40 cc density of water is 1 g/cc weight of water displaced =40*1 = 40 g therefore buoyant force = 40 g weight of marble in water = 100 - 40 = 60 g
