Henry's law states that :

p = k_H\ c

where p = partial pressure of the gas above the solution.
    k_H is the Henry's solubility constant for the solvent & solute at given T°C
    c = molar concentration  of the solute in the solution in  moles/Litre  at given T°C

p = 1 bar    and    k_H=71.18 kbar-Litre/mol
   c = 1  / 71.18 * 10³ = 14.048 mol/Litre

 concentration =  14.048 mol/Litre  or    28.096 gms/Litre
