    Hcl Stoichiometry
AI Thread Summary
The discussion centers on calculating the volume of hydrochloric acid (HCl) needed to react with sodium carbonate (Na2CO3). Participants express confusion over whether the 3.0 refers to moles or molarity, with a consensus leaning towards it being 3.0 M HCl, indicating a solution rather than a gas. To find the required volume, one must first determine the stoichiometric relationship from the balanced equation and calculate the moles of Na2CO3. If it were truly 3.0 moles, the context of the reaction would be irrelevant. Clarification on the concentration of HCl is essential for accurate calculations.

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.
 
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".
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
