Using this triangle for the information from the question, we can calculate how many moles of aluminium oxide 51 g is by using the formula number of moles = mass/formula mass. \(2A{l_2}{O_3} ...

3 \times 5\,moles\,{O_2}\\ = 15\,moles\,{O_2} \end{array}\) Use the information from the question to calculate how many ... Use the formula triangle once more to convert this number of moles ...
