Solution

The correct option is A $P = P_{A} + P_{B} + P_{C}$
According to Dalton's law of partial pressure,

Total pressure = sum of partial pressures of individual gases

$P_{t o t a l} = P_{a} + P_{b} + P_{c}$

Therefore, option A is correct.

If there unreactive gases having partial pressure PA,PB and PC and there moles are 1,2 and 3 respectively then their total pressure will be :

The correct option is A P=PA+PB+PCAccording to Dalton's law of partial pressure,Total pressure = sum of partial pressures of individual gasesPtotal=Pa+Pb+PcTherefore, option A is correct.
