We have to determine how many grams of Li3N can be produced from 1.75 mol of Li.

We will begin solving this problem by analyzing what information we have to solve this problem:

We will solve this problem through these steps:

  1. Find the molar mass of Li3N.
  2. Make a mole-to-mole comparison between Li and Li3N to find the number of moles of Li3N.
  3. Find the mass of Li3N using its number of moles and molar mass.
