Question

An Erlenmeyer flask contains 300 mL of water. A sample of 15.0 g of copper metal is dropped into the flask, raising the water level to 400 mL. What is the density of the copper sample?

Answer 1

The answer is 0.15 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 = 15 g

volume = final volume of water - initial volume of water

volume = 400 - 300 = 100 mL

We have

`density = (15)/(100) \\`

We have the final answer as

0.15 g/mL

Hope this helps you
