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 cm3volume of soil added to water = 350 cm3volume of water and soil after stirring = 800 cm3the percentage of air in the soil sample is

Answer Details

volume of air in the soil = (350 + 500) - 800
= 850 - 800 = 50 cm3
% of air in the soil = (volume of air)/total volume x (100)/1 = (50)/800 x 100 = 6.25%
