Answer:

Theoretical yield of CO₂ is 66 g

Step-by-step explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated:

C + O₂ —> CO₂

Next, we shall determine the mass of C that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of C = 12 g/mol

Mass of C from the balanced equation = 1 × 12 = 12 g

Molar mass of CO₂ = 12 + (16×2)

= 12 +32

= 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

12 g of C reacted to produce 44 g of CO₂.

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

12 g of C reacted to produce 44 g of CO₂.

Therefore, 18 g of C will react to produce = (18 × 44)/12 = 66 g of CO₂.

Thus, the theoretical yield of CO₂ is 66 g.
