I don't get the "then M HCl remaining - mols HCl/L soln" which numbers do I use here?:
This is what I've done so far: 2.40 g NaHCO3 / 84.01 g = 0.0285 mol NaHCO3 0.200 M * 0.150 L = 0.0300 mol HCl 0.0300 mol HCl - 0.0285 mol NaHCO3 = 0.0015 mol HCl remaining Now what? Which values do incorporate in the M of HCl?
Okay thank you, I understand now
If not, how can I find mol CO2
Because mol NaHCO3=mol CO2 produced
So will the mol value for PV=nRT be 0?
