A company dissolves 'x' amount of CO2 at 298 K in 1 litre of water to prepare soda water. X=×10-3 g. (nearest integer)

(Given: partial pressure of CO2 at 298 K=0.835 bar. Henry's law constant for CO2 at 298 K=1.67 kbar. Atomic mass of H,C and O is 1,12, and 6 g mol-1, respectively)

Answer:
1221.00
Solution:

Using Henry’s law
Pgas = KH .Xgas

10-3X0.835=1.67nCO2nCO2+55.510-3X0.5=nCO2nCO2+55.5nCO255.5=0.5 X10-3nCO2=27.75X10-3WCO2=27.75X10-3X44=1221X10-3g
