How much carbon dioxide is formed from 24.8 g of carbonic acid?

Mass = 17.6 g

Explanation:

Given dа ta:

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
