A lead weight used in the belt of a scuba diver has a mass of 226 g. When the weight is carefully placed in a large graduated cylinder containing 200.0 cm of water, the water level rises to 220.0 cm. What is the density of the lead weight (g/cm)?

11.3g/cm³

Explanation:

We first find the difference in volume which is

= 220 - 200 = 20 cm³

So volume of lead weight = 20 cm³

And we are given the mass of lead weight to be 226 g.

So we know that

Density = mass / volume

By substitution we have

d = 226 / 20

d = 11.3 g/cm³
