How many grams of zinc oxide can be produced from 7.3 moles of oxygen? *
1 answer:
Answer:
Mass = 1188.13 g
Explanation:
Given data:
Mass of ZnO produced = ?
Moles of oxygen = 7.3 mol
Solution:
Chemical equation:
2Zn + O₂ → 2ZnO
Now we will compare the moles oxygen and and ZnO.
O₂ ; ZnO
1 : 2
7.3 : 2/1×7.3 = 14.6 mol
Mass of ZnO:
Mass = number of moles × molar mass
Mass = 14.6 mol × 81.38 g/mol
Mass = 1188.13 g
