Question

A bottle of cold drink containing 200 ml of fluid is 0.1 molar in CO₂ . Assuming ideal behaviour for CO₂ , the volume of the gas at STP dissolved in the bottle is

(a)  2.24 litre

(b)  0.224 litre

(c)  0.448 litre

(d)  22.4litre

Answer 1

Correct option  (c) 0.448 litre

Explanation:

 1000 ml of solution contains .1 mole of CO₂ ;

200 ml of solution contains = 0.1/1000 x 200

= 0.02 mole CO₂

We know that,

Vol. of 1mole of CO₂ at STP = 22.4 litres;

Vol of 0.02 mole of CO₂ at STP = 0.448 litres
