1.	The total pressure of a mixture of oxygen and hydrogen is 1.0 atm、The mixture is ignited andthe water is removed. The remaining gas is pure hydrogen and exerts a pressure of 0.40 atmwhen measured at the same values of T and V as the original mixture. What was thecomposition of the original mixture in mole per cent?(a) xo, -0.2 xH2 0.8(c) xo2 - 0.6 xH2 0.4(b) Xo2 = 0.4; xH2-0.6(d) xo2 -0.8 xH2 0.2
