Question

What is the density of a sample of a substance with a volume of 120ml
and a mass of 90g?

Answer 1

Answer:

The answer is 0.75 g/mL

Explanation:

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

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

From the question

mass = 90 g

volume = 120 mL

We have

$density = \frac{90}{120} = \frac{9}{12} = \frac{3}{4}$

We have the final answer as

0.75 g/mL
