1L mixture of gases M and N is prepared by mixing gases from reservoirs of 10L of volume each. The initial pressures on the reservoirs are 100 and 50 bar respectively. After mixing, the pressures in the reservoirs are 99 and 49 bar respectively. What is the pressure (in bar) of the gas mixture at 27∘C ?
