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

Answer:

The answer is 0.15 g/mL

Explanation:

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

$density = \frac{mass}{volume}$

From the question

mass = 15 g

volume = final volume of water - initial volume of water

volume = 400 - 300 = 100 mL

We have

$density = \frac{15}{100}$

We have the final answer as

0.15 g/mL

Hope this helps you
