In an experiment to determine the percentage of air in a soil sample, the following readings were recorded:
volume of water in measuring cylinder = 500 cm3
volume of soil added to water = 350 cm3
volume of water and soil after stirring = 800 cm3
the percentage of air in the soil sample is
The total volume of soil = 350cm³
\(\frac{50}{350} × 100\)
= 14.28%
