Question

N2 and O2 amount is given .partial pressure of N2 is given..how to find the partial pressure of O2??

Answer 1

uppose we have gases A,B in a container of volume V. If we let PT to be the total pressure and PA , PB to be the partial pressures of the component gases in a mixture, the law of partial pressures can be written as

PT = PA +PB

 

In general, the total pressure of a mixture of gases is given by

PT = P1 + P2 + P3 + ..............

Where P1, P2, P3 .............. are the partial pressures of components 1, 2, 3
