Question

In the balanced equation, how many grams of lithium carbonate are produced from .66 moles of lithium phosphate and excess iron (II) carbonate?

3 FeCO₃ + 2 Li₂PO₄ —> 3 Li₂CO₃ + Fe₃(PO₄)₂

Answer 1

3 FeCO₃ + 2 Li₂PO₄ —> 3 Li₂CO₃ + Fe₃(PO₄)₂ ... balanced equation

Use the stoichiometry of the balanced equation along with dimensional analysis to solve this problem:

0.66 mol Li₂PO₄ x 3 mol Li₂CO₃ / 2 mol Li₂PO₄ x 73.89 g Li₂CO₃ / mol Li₂CO₃ = g Li₂CO₃

Just do the math.
