## Chemistry and Chemical Reactivity (9th Edition)

a) From Henry's law: $S=k_HP$ $S=0.0011\ mol/kg.bar\times0.21\ atm\times1.013\ bar/atm$ $S=0.0023\ mol/kg$ b) By Henry's law, if the partial pressure of butane is increased, its solubility in water will increase and so will its dissolved concentration.
