Answer:
54 moles
Explanation:
The balanced equation for the reaction is given below:
P4 + 6H2 → 4PH3
From the balanced equation above,
6 moles of H2 are needed to produce 4 moles of PH3.
Therefore, Xmol of H2 will be needed to produce 36 moles of PH3 i.e
Xmol of H2 = (6x36)/4
Xmol of H2 = 54 moles
Therefore, 54 moles of H2 are needed to produce 36 moles of PH3
