Answer» SOLUTION :SUPPOSE the partial pressures of `H_2 and O_2` in the GAS mixture are `p_1 and P_2` respectively. For `H_2 " gas : " P_1 V_1 = P_2 V_2` `0.8 xx 0.5 = P_1 xx 1 or P_1 = (0.8 xx 0.5)/1 = 0.4` bar For `O_2 " gas : " 0.7 xx 2.0 = P_2 xx 1` or `P_2 = (0.70 xx 2.0)/1 = 1.4` bar Hence, the total pressure of the gas mixture = `0.4 +1.4 = 1.8` bar
