Find m salt if 10 g of NaOH was consumed during neutralization with HCl.

m (NaOH) = 10 g.

Determine the mass of the resulting salt. We write down the solution.

First, we write down the equation of reactions.

HCL + NaOH = NaCl + H2O

Determine the molar mass of sodium hydroxide and sodium chloride.

M (NaOH) = 23 + 16 + 1 = 40 g / mol.

M (NaCl) = 23 + 35.5 = 58.5 g / mol.

Further, according to the reaction equation, we find the mass of the obtained salt.

10 g sodium hydroxide – x g sodium chloride

40 g / mol sodium hydroxide – 58.5 g / mol sodium chloride

X = 10 * 58.5: 40 = 14.625 g.

This means that the mass of the salt obtained is 14.625 grams.

Answer: m (NaCl) = 14.625 g.
