Aluminum is the most common metal in Earth's crust. But before the discovery in 1886 of the process that allowed it to be cheaply extracted from bauxite, aluminum was expensive to process. In 1852, a pound of aluminum cost $545. At those prices, $100 would buy only 83.2 g of aluminum in 1852. Determine the amount in moles that this masses of aluminum represent. ​
