Question

find the volume of co2 produced when 50g of calcium carbonate is heated​

Answer 1

Answer:

The volume is 11.2 litres.

Explanation:

Heating of CaCO3 is carried out according to following reaction:

CaCO3 - Cao + CO2 Molar mass of CaO = 56 g

Molar mass of CaCO, = 100 g =

Molar mass of CO2 = 44 g =

According to reaction, 1 mole of CaCO3 produces 1 mole of CO2 - 100 grams of CaCO3 produces 44

grams of CO2

→50 g of CaCO3 produces (44/100) x 50

= 22 grams

Mass of CO2 produced = 22/44 = 0.5 moles

Volume of CO2 = 22.4 x 0.5 moles = 11.2 Liters
