Answer:
Theoretical yield of NaCl = 877.5 g or 15 moles
Explanation:
Given data:
Number of moles of Na = 15 mol
Number of moles of Cl₂ = 15 mol
Theoretical yield of NaCl = ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Now we will compare the moles of Na and Cl₂ with NaCl.
Cl₂ : NaCl
1 : 2
15 : 2/1×15 = 30 mol
Na : NaCl
2 : 2
15 : 15
Less number of NaCl are produced by Na it will act as limiting reactant.
Theoretical yield:
Mass = number of moles × molar mass
Mass = 15 mol × 58.5 g/mol
Mass = 877.5 g
