Charcoal is primarily carbon. What mass of CO2 is produced if you burn enough carbon (in the form of charcoal) to produce 5.10×102kJ of heat? The balanced chemical equation is as follows:

C(s)+O2(g)→CO2(g),ΔH∘rxn=−393.5kJ

Express the mass in grams to three significant figures.

Step 1

The mass of CO2 produced when 5.10 x 102 kJ of energy is produced is calculated as,

393.5 kJ of energy is produced when one mole of CO2 is produced,

Moles of CO2 produced w...
