Homework Statement
A 1.0-L buffer solution is 0.105 M in HNO2 and 0.180 M in NaNO3. Determine the concentrations of HNO2 and NaNO3 after addition of 1.8 g HCl.

None
The Attempt at a Solution
I turned 1.8 g of HCl into mols and got 0.0494 mol of HCl. I subtracted this number from .105 M to find the new concentration of HNO2 and got 0.154 M. For NaNO3 I added 0.0494 and got 0.229 M but these answers were wrong. So what is the process to solve this problem?
