Answer:
There is 524 grams of K3N produced
Step-by-step explanation:
Step 1: Data given
Number of moles of potassium oxide (K2O) = 6 moles
Magnesium nitride (Mg3N2) = in excess
Step 2: The balanced equation
Mg3N2 + 3K2O → 3MgO + 2K3N
Step 3: Calculate moles of K3N
The limiting reactant is potassium oxide
For 1 mol of Mg3N2 we need 3 moles of K2O to produce 3 moles of MgO and 2 moles of K3N
For 6 moles of K2O we'll have 2/3 * 6 = 4 moles K3N
Step 4: Calculate mass of K3N
Mass K3N = 4 moles * 131 g/mol
Mass K3N = 524 grams
There is 524 grams of K3N produced
