What amount of a salt substance is formed by the interaction of 5 mol of potassium hydroxide and 5 mol of hydrochloric acid?

Given:
n (KOH) = 5 mol
n (HCl) = 5 mol

To find:
n (salt) -?

1) Write the equation of a chemical reaction:
KOH + HCl => KCl + H2O;
2) Compare the amount of potassium hydroxide substance and hydrochloric acid:
There is no excess or deficiency, so the substances will react completely;
3) Determine the amount of salt substance (KCl – potassium chloride) (taking into account the coefficients in the reaction equation):
n (KCl) = n (KOH) = n (HCl) = 5 mol.

Answer: The amount of potassium chloride substance is 5 mol.
