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

vol of water=500cm3
vol of soil added to water=350cm3
vol of water+soil=800cm3
vol of soil originally=800-500
=300cm3
vol of air in the soil=volume of soil added to water- volume of soil originally
=350-300
=50cm3
percentage%= (vol. of air in soil/vol of soil added to water)*100%
(50/350) * 100%
= 14.28%

The answer is 14.28%
Total volume of soil is 350cm³
50/350 ×100
= 14.28%
