Calculate the volume of 3.0 mol HCl required to react completely with 10.0g of Na2CO3.

Im confused about the "volume". What do they mean ?
Do I have to find the mass of HCl then convert it into a volume?

Are you sure it is not 3.0 M of HCl?

If it's volume, check out density after finding the stoichiometric constant for the balance equation and finding the mol of sodium bicarbonate.

If it is M (mol/L) you don't need density.

Stoichiometry Problem


unless you are forgetting that HCl is a gas unless specified otherwise (aqueous solution or sth); so by volume they mean the volume of the required gas under normal/standard conditions

But we're pretty sure the OP meant 3.0 M HCl, which does imply a solution, not a gas.

If it were really 3.0 moles as stated, it would be pointless to talk about the amount "required to react completely with 10.0g of Na2CO3".
