400 grams of NaOH2 reacts with HNO3. What is the mass of the salt.

univerkov | February 10, 2021 | education

In a chemical reaction

NaOH + HNO3 = NaNO3 + H2O

for every mole of alkali that reacts, the same amount of salt is formed

Let’s calculate the amount of substance in the reaction:

400/40 (molar mass NaOH) = 10 mol

We find the mass of salt in grams:

10 mol * 85 (molar mass of NaNO3) = 850 grams
