Given:
n (NaCl) = 3 mol

Find:
n (HCl) -?

1) Write the equation of a chemical reaction:
HCl + NaOH => NaCl + H2O;
2) Determine the amount of hydrochloric acid substance (taking into account the coefficients in the reaction equation):
n (HCl) = n (NaCl) = 3 mol;
3) Write the equation of a chemical reaction:
2HCl + Na2CO3 => 2NaCl + CO2 + H2O;
4) Determine the amount of hydrochloric acid substance (taking into account the coefficients in the reaction equation):
n (HCl) = n (NaCl) = 3 mol.

Answer: The amount of hydrochloric acid substance is 3 mol.
