Answer:
Mass = 0.92 g
Explanation:
Given data:
Mass of O₃ = 0.771 G
Mass of NO₂ = 0.663 g
Mass of NO₂ produced = ?
Solution:
Chemical equation:
O₃ + NO → NO₂ + O₂
Number of moles of O₃ :
Number of moles = mass/ molar mass
Number of moles = 0.771 g/ 48 g/mol
Number of moles = 0.02 mol
Number of moles of NO:
Number of moles = mass/ molar mass
Number of moles = 0.663 g/ 30 g/mol
Number of moles = 0.02 mol
Now we will compare the moles of NO₂ with NO and O₃ .
NO : NO₂
1 : 1
0.02 : 0.02
O₃ ; NO₂
1 : 1
0.02 : 0.02
Mass of NO₂:
Mass = number of moles × molar mass
Mass = 0.02 mol × 46 g/mol
Mass = 0.92 g
