Chapter 3.6, Problem 2CP

Determine the stoichiometric amount (in grams) of ${\text{O}}_{\text{2}}$ necessary to react with $\text{5}\text{.71 g}$ Al according to the following equation:

$4\text{Al}\left(s\right)+{\text{3O}}_{\text{2}}\left(g\right)\to {\text{2Al}}_{\text{2}}{\text{O}}_{\text{3}}\left(s\right)$

$\begin{array}{l}\text{1}\text{. 5}\text{.08 g}\hfill \\ \text{2}\text{. 9 03 g}\hfill \\ \text{3}\text{. 2}\text{.54 g}\hfill \\ \text{4}\text{. 4}\text{.28 g}\hfill \\ \text{5}\text{. 7}\text{.61 g}\hfill \end{array}$
