A bottle of cold drink has 200 mL liquid in which `CO_(2)` is 0.1 molar. If `CO_(2)` behaves as ideal gas the volume of `CO_(2)` at S.T.P. solution of cold drink is

Options

A. 22.4 L
B. 0.224 L
C. 2.24 L
D. 0.448 L

Answer

D

Explanation

Given,
Molarity = 0.1 M
Volume = 200 mL
`because`Molarity=`("number of moles of solute")/("volume of solution(mL)")xx1000`
`therefore` Number of moles`=(0.1xx200)/1000=0.02`
Now,
1 mole of dissolved `CO_(2)` occupies = 22.4 l volume at STP.
