In this case we can use the following expression, which is Raoult law:
Pa = XaPt
The Pt we can obtain it because we have the individual pressures so:
Pt = 437 + 376.9 + 86.3 = 900.2 Torr
Solving for Xa we have:
Xa = Pa/Pt
XH2 = 437/900.2 = 0.4854
XN2 = 376.9/900.2 = 0.4187
XAr = 86.3/900.2 = 0.0959
Hope this helps
