How many moles of sodium are needed to produce 3.5 moles of sodium oxide?
Step-by-Step
\begin{aligned} \underset{\text { Two SFs }}{3.5\ \cancel{moles\ Na_2O}} \times \frac{\overset{\text{Exact}}{4 \text { mole Na }}}{\underset{\text { Exact }}{2\ \cancel{moles\ Na_2O}} }=\underset{\text { Two SFs }}{7.0 \text { moles of Na }} \end{aligned}
| Given | Need | Connect |
| 3.5 moles of Na_2O | moles of Na | mole–mole factor |
