If 15 grams of Carbon dioxide is produced in a chemical reaction, how many grams of Carbon must be consumed in the reaction if w
Nata [24]

4.1g

Explanation:

Given parameters:

Mass of carbon dioxide = 15g

Mass of oxygen gas = 11g

Unknown:

Mass of carbon consumed = ?

Solution:

   Equation of the reaction:

                                              C +  O₂   →   CO₂

    To solve this problem from the balanced equation,  we have to use the amount of product formed and work to Carbon. This is because, we are sure of the amount of carbon dioxide formed but the amount of the given oxygen gas used is not precise.

  Number of moles of CO₂ = \frac{mass}{molar mass}

Molar mass of CO₂ = 12 + (16 x2) = 44g/mol

   Number of moles of CO₂ = \frac{15}{44} = 0.34mole

From the equation of the reaction;

              1 mole of CO₂  is produced from 1 mole of C

           0.34mole of CO₂  will produce 0.34mole of C

Mass of carbon reacting = number of moles x molar mass = 0.34 x 12 = 4.1g
