calculate the amount of hydrogen gas involved if ferrous + 2hcl = ferrous choloride + h2 if 55 gramme iron is reacting with 36.5 hydrochloric acid .

1 answer

Don't you mean
Fe + 2HCl -> FeCl2 + H2 ?
55g Fe is 0.984 moles
36.5 g HCl is 1.000 moles

HCl is slightly in excess of stoichiomentric.

0.984 moles of HCl are evolved.
That is 22 liters at STP
