Think about this.

PV = nRT for each gas, therefore, if we solve for n = PV/RT then

(PV/RT)<_{Ar} = (PV/RT)_{H2}. Then, since

n = grams/molar mass, we can write

(PV/RT)_{Ar} = (PV/RT)_{H2} = (g/MM)_{Ar} = (g/MM)_{H2}. Since P, V, R, and T are the same, we can dispense with the PV/RT and just write

(g/MM)_{Ar} = (g/MM)_{H2}.
