Stoichiometry - transferable mole values?

[skierboy]

Homework Statement

I have to find the mass of HCl (in grams) that is produced given the below reaction yields 18.7g of H₃PO₄.

Homework Equations

PCl₅ + 4H₂0 -> H₃PO₄ + 5HCl

The Attempt at a Solution

I calculated the # of mols for H₃PO₄.

I want to confirm if this mol value (0.190815119mol) is also the # of mol of H and # of mol of Cl, with regrards to HCl.. or is the number of mols of each of H and Cl fives times that of 0.190815119mol because of the coefficient "5"HCl ?

Thanks!

Calculate formula weight of phosphoric acid; use this to find moles of phosphoric acid.
Use stoichiometric mole ratio found in the reaction statement to calculate moles of resulting HCl.
Calculate formula weight of HCl and use this to calculate the mass of HCl.

The chemical equation says that for each mole of PCl₅ consumed you get 5 moles of HCl, so you would need to multiply 0.191 mol by 5 to get the number of moles of HCl.

Alrighty, thanks for the clarification!
