Answer:
Volume = 1.23 cm³
Explanation:
We can solve this problem by keeping in mind the following <em>definition of density</em>:
We<u> input the density and mass given by the problem</u>:
- 2.70 g/cm³ = 3.32 g / Volume
And <u>calculate the volume</u>:
- Volume = 3.32 g ÷ 2.70 g/cm³
The answer is 1.23 cm³.
