Question

a piece of lead with a mass of 25 g causes the water level in the graduated cylinder to rise 3mL. What is the density of the piece of lead?

Answer 1

Density is given by the formula
`D= (m)/(v)`, where D is equal to the density, m is mass of lead and v the volume of lead.

Since we are not given an initial volume the change in volume is caused by the piece of lead which is a 3ml.

Therefore,

`D=(m)/(v) =(25)/(3)= 8.33 g/ml`
