Answer:
32cm³
Explanation:
Given parameters:
Density of substance = 2.7g/cm³
Mass of substance = 86.4g
Unknown:
Volume of substance = ?
Solution:
Density is the mass per unit volume of a substance.
Density =
Since the unknown is volume we solve for it;
mass = density x volume
86.4 = 2.7 x volume
volume = = 32cm³
