5 g×1 g17.03 mol

5g times 1 g over 17 point 03 mol

5 g×17.03 mol1 g

5g times 17 point 03 mol over 1g

5 g×1 mol17.03 g

5g times 1 mol over 17 point 03g

5 g×17.03 g1 mol

5g times 17 point 03g over 1 mol

Answer 1

Correct choice: 5 g × (1 mol / 17.03 g).

Calculation: 5 / 17.03 = 0.2936 mol ≈ 0.294 mol of NH3.
