Question

A stone is dropped in a graduated cylinder. Then,30mL of water are poured in the cylinder. The level of volume reads 55.25mL of total volume. Please Find: a) The volume of the stone in cubic centimeters b)The density of the stone if it's mass is 160 grams A stone is dropped in a graduated cylinder. Then,30mL of water are poured in the cylinder. The level of volume reads 55.25mL of total volume. Please Find: a) The volume of the stone in cubic centimeters b)The density of the stone if it's mass is 160 grams a) The volume of the stone in cubic centimeters b)The density of the stone if it's mass is 160 grams

Explanation / Answer

a) volume of stone =volume of water displaced according to Archimedes principles

=>Vstone = 55.25mL-30mL =25.25mL =25.25*10^-3L

=>V = 25.25*10^-3*10^-3 m^3 =2.525 *10^-5 m^3 (since 1L =10^-3m^3)

b) density d =m/V =0.16kg/(2.525 *10^-5) =6336.63 kg/m^3
