The frame of a bicycle contains 6500 g of aluminum. How many moles of aluminum are in the bicycle frame?
Equality : 1 mole of Al = 26.98 g of Al
Conversion Factors: \frac{26.98\ g\ Al }{1\ mole\ Al } \text { and } \frac{1\ mole\ Al }{26.98\ g\ Al }
Step-by-Step
\begin{aligned} \underset{\text { Two SFs }}{6500\ \cancel{g\ Al}} \times \frac{\overset{\text{Exact}}{1 \text { mole Al }}}{\underset{\text { Four SFs }}{26.98\ \cancel{g\ Al}} }=\underset{\text { Two SFs }}{240 \text { moles of Al }} \end{aligned}
