Answer:
Mass of oxygen = 61.824 g
Mass of carbon dioxide = 85.01 g
Explanation:
Given data:
Mass of glucose = 58 g
Mass of carbon dioxide = ?
Mass of oxygen = ?
Solution:
First of all we will write the balanced chemical equation,
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
Moles of glucose:
Number of moles = mass / molar mass
Number of moles = 58 g/180 g/mol
Number of moles = 0.322 mol
Now we compare the moles of oxygen with glucose from balance chemical equation.
C₆H₁₂O₆ : O₂
1 : 6
0.322 : 0.322×6 = 1.932 mol
Mass of oxygen:
Mass of oxygen = number of moles × molar mass
Mass of oxygen = 1.932 mol × 32 g/mol
Mass of oxygen = 61.824 g
Now we compare the moles of carbon dioxide with moles of glucose and oxygen.
C₆H₁₂O₆ : CO₂
1 : 6
0.322 : 0.322×6 = 1.932 mol
O₂ : CO₂
6 : 6
1.932 : 1.932
Mass of carbon dioxide;
mass of carbon dioxide = number of moles × molar mass
mass of carbon dioxide = 1.932 mol × 44 g/mol
mass of carbon dioxide = 85.01 g
