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
Hope this helps you
