Answer:

0.64 g/mL

Explanation:

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

[tex]d = \frac{m}{v} \\ [/tex]

m is the mass

v is the volume

From the question

m = 45 g

v = 70 mL

We have

[tex]d = \frac{45}{70} = \frac{9}{14} \\ = 0.6428571...[/tex]

We have the final answer as

0.64 g/mL
