Question

Given the following unbalanced equation: Na2O+H2O -> NaOHhow many moles of NaOH are produced from 1.20 moles of Na2O?

Answer 1

The first step we have to follow is to balance the given equation, making the number of atoms of each element equal in both sides of the equation.

$Na_2O+H_2O\to2NaOH$

Now, that the equation is balanced, we can use the stoichiometric ratio of Na2O to NaOH to find the number of moles of NaOH produced from 1.20moles of Na2O:

$1.20molNa_2O\cdot\frac{2molNaOH}{1molNa_2O}=2.40molNaOH$

2.40 moles of NaOH are produced.
