How Do You Calculate Moles in a CaCO3 and HCl Reaction?

[Elizabeth12]

Hi

I'm stuck on a homework question on moles. I know the mole formula, but the question doesn't state any needed numbers.

Question: Calculate the number of moles of calcium carbonate and hydrochloric acid at the start of the reaction.

the reactions is CaCO3+2HCL---CaCl2+CO2+H2O

How do you calculate the number of moles?

Please help me answer this question a.s.a.p. This homework is due on monday!
Thanks.

If that's the complete question, there is no answer. But I guess you may have omitted part of the question that you think is irrelevant, while in fact it is.
