Question

4. What is the density of a substance that weighs 45 g and is 70 mL?
(Density = g/mL)

Answer 1

Answer:

0.64 g/mL

Explanation:

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

$d = \frac{m}{v}$

m is the mass

v is the volume

From the question

m = 45 g

v = 70 mL

We have

$d = \frac{45}{70} = \frac{9}{14} \\ = 0.6428571...$

We have the final answer as

0.64 g/mL
