Answer: -
44 g
Explanation: -
Mass of Carbon = 12 g.
Molar mass of carbon = 12 g / mol
Number of moles of C = [tex] \frac{12 g}{12 g / mol} [/tex]
= 1 mol
Molar mass of O₂ = 16 x 2 = 32 g / mol
Number of moles of O₂ = [tex] \frac{32 g}{32 g / mol} [/tex]
= 1 mol
The balanced chemical equation for this process is
C + O₂ →CO₂
From the equation we see
1 mol of C reacts with 1 mol of O₂
Here both the reactants are present in required amounts.
Now we see again from the balanced equation
1 mol of C gives 1 mol of CO₂
Molar mass of CO₂ = 12 x 1 + 16 x 2 = 44 g / mol
Mass of CO₂ formed = number of moles x molar mass
= 1 mol x 44 g / mol
= 44 g
