Given total number of mole = 3 + 1 = 4
PV  = nRT 
at S.T.P.   V = 22.4 L
                T = 273 K 
                R = 0.0821 L atm K^-1 mol^-1
  P = 4* 273*0.0821/22.4
     = 4.002375 atm 
 partial pressure of O2 = 3*4.002375 / 4 
                                  = 3.0018 atm 
 partial pressure of H2 = 1*4.002375 / 4
                                 = 1.0006 atm
