Answer:
C) It depends on the relative molecular masses of X, Y and Z.
Explanation:
Dalton´s law for the partial pressure of an ideal gas in a mixture is given by the relationship :
Pa = Xa Ptotal,
where Xa is the mole fraction of gas A times the total pressure ( Pa + Pb + Pc...)
The mole fraction is, in turn, given by
Xa = mol A / total # moles
Since the moles of a substance is the mass divided by its molecular weight , it follows that answer C) is the correct one.
