Question

Zn + 2HCl -> ZnCl2 + H2

If 7.29 g of Zinc reacted, how many liters of HCl were used?

I know that i can't use mass volume conversion, because the HCl is not a gas...so what do i do?

Answer 1

Very observant. Obviously the person making up the question meant to include a molarity of HCl but didn't. No way to work the problem.

Answer 2

okay, thank you!
