10.0 g of calcium carbonate was heated. The mass of calcium oxide left was 5.6 g. Calculate the mass of

carbon dioxide produced in the reaction.

CaCO3 (s) + Cao (s) + CO2 (g)

4.4g

Explanation:

Calculate the molar mass of CaCO3

40+12 + (16*3)

40+12+48

100 g/mol

Calculate the molar mass of CO2

12 + (16*2)

12+32

44g/mol

100g of CaCO3=44g of CO2

10g of CaCO3=10*44/100

g of CO2=440/100

=4.4g of CO2

4.4g

Explanation:

Mass of CaCO3 = 10g

Mass of CaO = 5.6g

Mass of CO2 = ?

Mass of CaCO3 = Mass of CaO + Mass of CO2

Mass of CO2 = Mass of CaCO3 - Mass of CaO

Mass of CO2 = 10 - 5.6

Mass of CO2 = 4.4g
