Followings are measured for a soil sample:

total mass (gram) = 23.3 gram,

total volume (cm^3) = 12

Then the sample is put in an oven to dry. After drying, followings are given:

oven-dry solid mass (gram) = 21.2

oven-dry solid density (gram/cm^3) = 2.5

Determine the porosity of the soil sample before oven dry.
