A bottle full of water has mass of 100g. when the same bottle is filled with luquid X, its mass is found to be 80g.If the mass of an empty bottle is 50g, calculate the density of the liquid?

subtracting the bottle mass
water=50g
X=30 g
so the density of the liquid X is 30/50 times the density of water.
