A 300 mL bottle of soft drink has

0.2 M CO_{2}

dissolved in it. Assuming

CO_{2}

behaves as an ideal gas, the volume of the dissolved

CO_{2}

at STP is ______ mL. (Nearest integer)

Given: At STP, molar volume of an ideal gas is

22.7 L mol^{- 1}

Answer: 1362

The amount of dissolved carbon dioxide is

n = 0.2 M \times 0.300 L = 0.06 mol

. At STP each mole of an ideal gas occupies

22.7 L

, so the volume is

0.06 \times 22.7 = 1.362 L

. Converted to millilitres, the dissolved carbon dioxide would occupy

1362 mL

at STP.
