Answer: 52.4 grams
Explanation:
The two reactants PCl5 and H2O, must occur in a 1:4 ratio, so that tells us, that we need 4 times more H₂O than phosphorus pentachloride.
0.287 moles PCl5 multiplied by 4 equal 1.15 moles H2O. That tell sus that 1.15 moles H2O is needed.
Because we have 3.84 moles H2O, the PCL5 is the limiting reactant.
0.287 mol PCl₅ x (5 mol HCl divided by 1 mol of PCl₅) x ( 36.5g HCl divided by moles of HCl) = 52.4 g of HCl is formed
(Hopefully this helps!)
