Coal power plants burn large amounts of coal Cs in an O2g at

Coal power plants burn large amounts of coal, C(s), in an O2(g) atmosphere to generate electricity. The chemical reaction responsible for producing this energy is shown below: C(s) + O2(g) CO2(g) Determine the mass in grams of CO2 produced when 105 metric tons of C(s) are completely burned in an O2 atmosphere (1 metric ton = 103 kg = 106 g). Don\'t include units in your answer

Solution

The given reaction is :

C + O2 - - - - - - > CO2

Here C is the limiting reagent,

So, amount of CO2 produced = (mass of C / molar mass of C) * ( mole of C/ mole of CO2) * molar mass of CO2

Amount of CO2 Produced = (105 tons) / (12.01g /mol) x (1 mol CO2 / 1 mol C) x (44.009g /mol)

Amount of CO2 Produced = 384.75 metric tons

Now 1 metric ton = 10^6 grams

So, 384.75 ton = 384.75 * 10^6 g = 3.84 * 10^8 g CO2
