Question

The mass of a lead piece is 105g. When it is immersed into a measuring cylinder, the water level rises from 50 ml to 60 ml mark. Find: i The volume of the lead piece
ii The density of the lead in kg/m​

Answer 1

Answer:

The mass of a lead piece is 115 g. When it is immersed into a measuring cylinder, the water level rises from 20 ml mark to 30 ml mark. Find:

(i) the volume of the lead piece,

(ii) the density of the lead in kg m-3

Answer 2

Explanation: volume of the 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, the density of the lead piece is 11500 kg/m cube
