Calculate the number of oxygen atoms required to combine with 7.0g of N₂ to form N₂O₃ if 80% of N₂ is converted into products. N O N O →
A.3.24 × 1023
B.3.6 × 1023✓ Correct
C.18 × 1023
D.6.02 × 1023
Explanation
2 2 2 3 3 2 N O N O → 1 mol of 2 N combine with 1.5 mole of 2 O 2 2 7 80 moles of N needs 0.3 mol of O 28 100 x 23 23 2 2 0.3 moles of O 6.022 10 0.3 1.8 10 molecules of O x x x . Therefore, No. of O-atoms =2×0.3× 23 23 6 10
