Answer:
The density should be 2.8 g/mL.
Step-by-step explanation:
To solve this problem, we must remember that we find density using the following formula:
Density = mass/volume
Therefore, if we plug in the values we are given in the problem, we get:
Density = 70 g / 25 mL
Density = 2.8 g/mL
Therefore, the correct answer is 2.8 g/mL.
Hope this helps!
