Answer:
Porosity of sample = 25%
Explanation:
Given:
Total volume = 400 cubic centimeters
Pore space volume = 100 cubic centimeters
Find:
Porosity of sample
Computation:
Porosity of sample = [Pore space volume / Total volume]100%
Porosity of sample = [100 / 400]100%
Porosity of sample = [1/4]100%
Porosity of sample = [0.25]100
Porosity of sample = 25%
