Question

For the following reaction, how many moles of NaOH will be produced if you react 2.4 moles of Na2O?Na2O + H2O → 2 NaOH

Answer 1

1) Balance the chemical equation.

`Na_2O+H_2O\rightarrow2NaOH`

2) Moles of NaOH produced.

The molar ratio between Na2O and NaOH is 1 mol Na2O: 2 mol NaOH.

`mol\text{ }NaOH=2.4\text{ }mol\text{ }Na_2O*\frac{2\text{ }mol\text{ }NaOH}{1\text{ }mol\text{ }Na_2O}=4.8\text{ }mol\text{ }NaOH`

The number of moles of NaOH produced in the reaction is 4.8 mol NaOH.
