Find the mass of the formed salt as a result of the interaction of 30 grams of 10% hydrochloric acid solution

Find the mass of the formed salt as a result of the interaction of 30 grams of 10% hydrochloric acid solution with sodium hydroxide.

Find the molar amount of hydrochloric acid. For this purpose, we divide its weight by its molar weight.

M HCl = 1 + 35.5 = 36.5 grams / mol; N HCl = 30 x 0.1 / 36.5 = 0.082 mol;

Let us determine the mass of 0.082 mol of sodium chloride.

M NaCl = 23 + 35.5 = 58.5 grams / mol; m NaCl = 0.082 x 58.5 = 4.797 grams;
