The answer to the problem

Question

Use the following balanced equation to answer the question:             2NaOH + H₂SO₄ ------> 2 H₂O + Na₂SO₄

How many grams of H₂O is produced from a reaction that uses 6 moles of NaOH?

Answer 1

2NaOH + H2SO4 ==> 2H2O + Na2SO4 .. balanced equation

First, use the stoichiometry of the equation to find the moles of H2O formed:

6 mols NaOH x 2 mols H2O / 2 mols NaOH = 6 mols H2O

Next, convert mols H2O to grams:

6 mols H2O x 18 g H2O / mole = 108 g H2O
