what is the theoritical value of the concentration of HCL Vin molarity and g/li when it is reacted with 0.4M of sodium hydroxide and the average volume of NaOH is 27.2ml?
mols NaOH = M x L = ?
mols HCl = mols NaOH
M HCl = mols HCl/L HCl.
Convert mols to grams for g/L.
g HCl = mols HCl x molar mass HCl.
