1. Write all possible mole ratios for the reaction: 2A1,03 ( 4A1 + 302. There are a total of six different ratios, including reciprocals. Make sure each ratio has the correct coefficient and unit
of "moles".
Use the conversions from problem #1, to calculate the following. Make sure to show all units,
conversion factors and correct number of significant figures.
