| What is the maximum mass of sodium hydroxide that can be obtained from sodium oxide by a chemical amount of 0.56 mol.
To solve it, we will compose an equation, indicate the coefficients:
Na2O + H2O = 2NaOH – hydration reaction, sodium hydroxide obtained;
Let’s determine the molar masses of substances:
M (Na2O) = 61.8 g / mol;
M (NaOH) = 39.9 g / mol;
Let’s calculate the number of moles of sodium hydroxide:
0.56 mol (Na2O) – X mol (NaOH);
-1 mol -2 mol hence, X mol (NaOH) = 0.56 * 2/1 = 1.12 mol;
We find the mass of sodium hydroxide by the formula:
m (NaOH) = Y * M = 1.12 * 39.9 = 44.68 g.
Answer: in the course of the reaction, sodium hydroxide with a mass of 44.68 g was obtained.
