Question

Calculate the mole fraction of CO2 in one litre of soda water sealed under a pressure

of 3.5 bar at 298 K. KH = 1.67 103

bar.​

Answer 1

Explanation:

Pa

Pressure of , ρ = 2.5 atm = 2.5 × 101325 Pa

ρ = × χ

⇒ χ = =

χ = 1.517 ×

⇒ =

⇒ = 1.517 ×

[ ∵ < < < ]

∴ It can be neglected in the denominator.

⇒ = 1.517 ×

⇒ =

=

= 4.214 × moles

= 42.14 × moles

= 42.14 millimoles
