Question

___Li + ___AlPO4 --> ___Al + ___Li3PO4

If 2.3 moles of Aluminum Phosphate are reacted, how many grams of Lithium Phosphate are produced?

Answer 1

266.3 g

Step-by-step explanation:

• __Li + __AlPO₄ → __Al + __Li₃PO₄

The balanced reaction is:

• 3Li + AlPO₄ → Al + Li₃PO₄

First we convert 2.3 moles of AlPO₄ to moles of Li₃PO₄, using the stoichiometric coefficients:

• 2.3 mol AlPO₄ *
  `(1molLi_3PO_4)/(1molAlPO_4)` = 2.3 mol Li₃PO₄

Then we convert Li₃PO₄ moles into grams, using its molar mass:

• 2.3 mol Li₃PO₄ * 115.79 g/mol = 266.3 g
