Question

Henry’s law is important in environmental chemistry,
where it predicts the distribution of pollutants between
water and the atmosphere. Benzene (C6H6) emitted in
wastewater streams, for example, can pass into the air,
where it is degraded by processes induced by light from
the sun. The Henry’s law constant for benzene in water at
25°C is 301 atm. Calculate the partial pressure of benzene
vapor in equilibrium with a solution of 2.0 g of benzene
per 1000 L of water. How many benzene molecules are
present in each cubic centimeter?
