Question

4 Al + 3 O₂ --> 2 Al2Ol₃ Given 6 moles of aluminum, how many grams of aluminum oxide will be produced?

Answer 1

305.88 g

Step-by-step explanation:

4 Al + 3 O₂ → 2 Al₂O₃

First, we convert 6 moles of aluminum (Al) into moles of aluminum oxide (Al₂O₃), using the stoichiometric coefficients:

6 mol Al *
`(2molAl_2O_3)/(4molAl)` = 3 mol Al₂O₃

Finally we convert 3 moles of aluminum oxide into grams, using its molar mass:

3 mol Al₂O₃ * 101.96 g/mol = 305.88 g
