If dry air is considered to have average molecular mass 28.84. What is the composition of dry Air?

Air contains nitrogen and oxygen in the volume ratio of 4:1 . The average molecular weight of air is

What are the components of clean, dry air?

What is the percentage of Nitrogen and Oxygen in the air?

What is the % composition of nitrogen by weight in air ?

Write towe advantages of having oxygen in air.

Consider air is composed of 4 parts of nitrogen and 1 part of oxygen. At S.T.P., speed of sound in dry air in 332 rad/s. If the ratio of densities of oxygen and nitrogen at S.T.P. is 16 : 14, calculate the velocity of sound in nitrogen under similar conditions.
