Question

the mass 01
The mass of a lead piece is 115
Find :
(i) the volume of the lead piece,
(ii) the density of the lead in kg m-3
be its density in kg m-3 ?
immersed into a measuring cylinder, the we
level rises from 20 mL mark to 30 mL me
Ans. (i) 10 cm (ii) 11500 kg
The density of copper is 8.9 g cm. What​

Answer 1

Answer:

volume of lead piece is 10 ml

1 ml= 1/1000 L

10 ml = 10 to the power -2 L

Now,

mass of lead piece is 115 X 10 to the

power -3 kg

so, Density of lead piece = 115 X 10 to the power -3/10 to the power -2

So, density of lead piece is 11500 kg/m cube
