Question

the mass of a lead piece is 115g. when it is immersed into a measuring cylinder, the water level rises from 20ml to 30ml. find the volume of lead piece and the density of lead in kg m-3

Answer 1

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

Answer 2

Answer:

volume of the lead pice 10mL

1ml =1\1000 L

10ml =10 to power -2 L

now

mass of lead piece is 115 x 10 to the

power -3 kg

soDensity of lead piece =115 x 10 to

the power 3\10 to the power -2

so density of lead piece 11500 kg \ m

cube
