1.	37Equal masses of methane and hydrogen are mixed in an empty container at 25 C. lhe traction ofpressure exerted by hydrogen isA) 732gofoogen (Al wt=16)and 0.2 g of hydrogen (At wt. "I)are placed in a l 121, flaskor te161738
Answer» <p>Let x grams of each hydrogen and methane are mixed, Moles of H2 = x/2 Moles of CH4 = x/16 ⇒ Mole-fraction of H2 = (x/2)/(x/2 + x/16) = 8/9 ⇒ (Partial pressure of H_2)/(Total pressure) = mole-fraction of H2 = 8/9</p>
