6kg of coal (carbon) is burned in air. What mass of carbon dioxide will be produced? (Assume that combustion is complete and ign
Flauer [41]

The mass of carbon dioxide that would be produced will be 22 kg

<h3>Combustion of carbon</h3>

The combustion of carbon in air can be represented by the equation:

C + O2 ---> CO2

The mole ratio of C to O2 to CO2 is 1:1:1.

Mole of 6kg of carbon = mass/molar mass

                                      = 6000/12

                                      = 500 moles

Equivalent mole of CO2 produced = 500 moles

Mass of 500 moles CO2 = mole x molar mass

                                          = 500 x 44.01

                                           = 22,005 g or 22 kg approximately
