Question

A nitric acid solution of unknown concentration is used to titrate 0.771g of sodium tyrosinate (NaC9H10NO3). If the endpoint is reached when 32.79mL of nitric acid has been added, what is the concentration of the unknown nitric acid solution?

I assume this is a 1:1 reaction.
mols C compound = grams/molar mass
mols HNO3 = same
M HNO2 = mols HNO3/L HNO2
