Question

A graduated cylinder is filled with 50.7 mL of water. If a 10.0 g piece of zinc metal is added to the water, and the volume rises to 52.1 mL, what is the density of the metal?

Answer 1

The answer is 7.14 g/mL

Step-by-step explanation:

The density of a substance can be found by using the formula

`density = (mass)/(volume) \\`

From the question

mass = 10 g

volume = final volume of water - initial volume of water

volume = 52.1 - 50.7 = 1.4 mL

We have

`density = (10)/(1.4) \\ = 7.142857...`

We have the final answer as

7.14 g/mL

Hope this helps you
