what is the partial pressure of hydrogen in a flask containing 2g hydrogen and 32g sulphur dioxide

Is this at STP? If not what is the volume or total pressure?
mols H2 = grams/molar mass
mols SO2 = grams/molar mass

total mols = mols H2 + mols SO2
XH2 = mols H2/total mols
XSO2 = mols SO2/total mols

pH2 = XH2*Ptotal
XSO2 = XSO2*Ptotal
The total pressure is equal to sum of partial vapour pressures then how u use this formula ??
