Question 3 • Chemistry

If 6 point 0 0 g of carbon is burned completely, what volume of carbon dioxide gas is released at STP?

Answer
A
6 point 0 liters
B
22 point 4 liters
C
11 point 2 liters
D
134 point 4 liters

Explanation

Carbon burns according to C + O₂ → CO₂, so 1 mole of carbon produces 1 mole of carbon dioxide. Since carbon has a molar mass of 12 g/mol, 6.00 g is 6.00 ÷ 12 = 0.50 mol. At STP, 1 mole of gas occupies 22.4 L, so 0.50 mol of CO₂ occupies 0.50 × 22.4 = 11.2 L. The correct choice is 11.2 liters.
