How many moles is 6.2 grams of P?
How many moles is 4grams of H2?
Notice in the balanced reaction it takes 1.5 moles of H2 for every one mole of P.
If you have more of H than that, then the limiting reactant is P, otherwise the limiting reactant is H2.
Use the moles of the limiting reactant to determine the moles of PH3.
