Okay so I got this question on my practice exam and there is a conversion factor that I do not understand or better I don't know where they got it from if someone knows please explain
consider the unbalanced reaction Na2CO3 +HCl--> CO2 + H2O + NaCl
for this reaction, how many ml of a 2M solution of Na2CO3 are required to produce 11.2L of CO2 at STP?
1. I know i gotta balance the eq
2. Use stp at 224 L
3. convert to moles of Co2
4. then moles if Na2CO3
5??? this is where i'm stuck the explanation states that for ever 1mol of Sol'n there are 2moles of Na2Co3 where is the 2 coming from? I don't have a 2 as a coefficient where I balance it i have a 1:1 ratio
if you get my question and understand my dilemma please explain. thanks
