Question 10 • IN-Chemistry B

If 6.00 g of carbon is burned completely, what volume of carbon dioxide gas is released at STP?

Answer
A
6.0 L
B
11.2 L
C
22.4 L
D
134.4 L

Explanation

Complete combustion follows C + O₂ → CO₂, so each mole of carbon produces one mole of carbon dioxide. The 6.00 g of carbon is 6.00 g ÷ 12.0 g/mol = 0.500 mol; at STP, that amount of gas occupies 0.500 × 22.4 L = 11.2 L. The correct choice is 11.2 L.
