A \( 300 \, \text{mL} \) bottle of soft drink has \( 0.2 \, \text{M} \) \( \mathrm{CO_2} \) dissolved in it. Assuming \( \mathrm{CO_2} \) behaves as an ideal gas, the volume of the dissolved \( \mathrm{CO_2} \) at STP is ________ \( \text{mL} \). (Nearest integer)
[Given : At STP, molar volume of an ideal gas is \( 22.7 \, \text{L mol}^{-1} \)]
