Q.

A 300 mL bottle of soft drink has 0.2 M CO2 dissolved in it. Assuming CO2 behaves as an ideal gas, the volume of the dissolved CO2 at STP is ______ mL. (Nearest Integer)

Given: At STP, molar volume of an ideal gas is 22.7 L mol-1.                     [2023]


Ans.

(1362)

Number of moles of CO2=M×V×10-3

                                                 =0.2×300×10-3=0.06 mole

Volume of CO2 (at STP)=0.06×22.7

                                                =1.362 L=1362 mL
