Answer:
Mass = 7.2 g
Explanation:
Given data:
Mass of ZnO = 36.9 g
Mass of oxygen needed = ?
Solution:
Chemical equation:
2Zn + O₂ → 2ZnO
Number of moles of ZnO:
Number of moles = Mass/ molar mass
Number of moles = 36.9 g/81.38 g/mol
Number of moles = 0.45 mol
Now we will compare the moles of ZnO with oxygen:
ZnO : O₂
2 : 1
0.45 : 1/2 × 0.45 = 0.225
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.225 mol × 32 g/mol
Mass = 7.2 g
