Can anyone "caluculate the number of moles of hydrogen chloride produced from 10 moles of hydrogen"?

H₂(g) + Cl₂(g) =(yields) 2HCl(g)

And: "Calculate the # of moles of chlorine needed to form 14 moles of iron(III) chloride"?

2FE(s) + 3Cl₂(g) =(yields) 2FeCl₃(s)

And: "Calculate the number of grams of nitrogen dioxide that are produced from 4 moles of nitric oxide"?

2NO(g) + O₂(g) =(yields) 2NO₂(g)

Thank you!!!!!!!!!!!!

It must be:
1 mol H₂-----------2moles HCl
10 moles H₂-------x
x= 20moles HCl

3moles Cl₂---------2moles FeCl₃
x--------14moles FeCl₃
x= 21moles Cl₂

2molesNO--------92g NO₂
4molesNO--------x
x= 184g NO₂



2K₃PO₄ + 3MgCl₂-----6KCl + 1Mg₃(PO₄)₂
2Fe(NO₃)₃ + 3Na₂CO₃-----1Fe₂(CO₃)₃ + 6NaNO₃
