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

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

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
