The concentration (c) of a gas at pressure (p) at a given temperature (T) through the Henry's constant kH
c = kH * p
at 20 C or 293 K, the henry's constant kH for CO2 = 0.037 mol/L-atm
Given concentration c = 0.0580 moles/L
Hence the pressure is given as:
p = c/kH = 0.0580 molesL-1/0.037 molL-1atm-1 = 1.57 atm
Pressure required is 1.57 atm
