Answer:
Mass = 17.6 g
Explanation:
Given data:
Mass of carbonic acid =24.8 g
Mass of carbon dioxide form = ?
Solution:
Chemical equation:
H₂CO₃ → CO₂ + H₂O
Number of moles of carbonic acid:
Number of moles = mass/ molar mass
Number of moles = 24.8 g / 62.03 g/mol
Number of moles = 0.4
Now we will compare the moles of CO₂ with H₂CO₃.
H₂CO₃ : CO₂
1 : 1
0.4 : 0.4
Mass of CO₂ :
Mass = number of moles × molar mass
Mass = 0.4 mol × 44 g/mol
Mass = 17.6 g
