Question

The mass of lead piece is 400g. when it is immersed into a measuring cylinder, the water level [2] rises from 30ml to 50ml mark. find 1) volume of lead piece 2) density of metal piece in
g/cm^3

Answer 1

Explanation:

volume of lead piece = V=v_2-v_1

v_{1\ }=\ 20\ ml\ ,\ v_2\ =\ 30\ ml

= 30 - 20 ml = 10 ml

(ii) density of lead piece = d=\frac{M}{V}

= \frac{115}{10}

= 11.5\ kg\ cm^{-3}
