Solutions Question 10

Question 10 - 30 January - Shift 1

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 $22.7 L mol^{-1}$

Show Answer

Answer: (1362)

Solution:

Mole of $CO_2=0.2 M \times(300 \times 10^{-3}) L$

$ =0.06 \text{ Mole } $

Volume of 0.06 mole $CO_2$ at S.T.P

$ \begin{aligned} & =0.06 \times 22.7 \\ & =1.362 L \end{aligned} $
