How many grams of salt is formed when 245 g of phosphoric acid reacts with sodium hydroxide?

Let’s compose the chemical equation for the reaction of phosphoric acid with sodium hydroxide.

H3PO4 + 3NaOH = Na3PO4 + 3H2O.

Let us find the molar masses of phosphoric acid and sodium phosphate salt.

M = 0.098 is the molar mass of phosphoric acid.

m = 0.118 is the molar mass of the salt.

In order to find the mass of sodium phosphate salt, you need to solve the equation.

0.245: 0.098 = X: 0.118. From here we find X, where X is the mass of sodium phosphate salt.

X = 0.245 * 0.118: 0.098 = 0.295.

This reaction produces 0.295 kilograms of sodium phosphate salt.
