Question

A piece of copper of mass 106 g is dipped in a measuring cylinder containing water at 22 ml mark. The water rises to 34 ml mark. Find (a) volume of the copper piece (b) the density of copper.

Answer 1

(a) Volume of the copper piece,`V=34ml-22ml`
`=12ml`
`=12cm^3`
(b) Density of copper, `d=("mass of copper piece"(M))/("volume of copper piece"(V))`
`=(160g)/(12cm^3)=8.83(g)/(cm^2)`
`=8.83xx1000(kg)/(m^3)`
`=883(kg)/(m^3)`
