Solutions of hydrogen in palladium may be formed by exposing pd metal to h gas. the concentration of hydrogen in the palladium depends on the pressure of h gas applied, but in a more complex fashion than can be described by henry’s law. under certain conditions, 0.94 g of hydrogen gas is dissolved in 215 g of palladium metal.

(a) determine the molarity of this solution (solution density = 10.8 g/cm3).

(b) determine the molality of this solution (solution density = 10.8 g/cm3).

(c) determine the percent by mass of hydrogen atoms in this solution (solution density = 10.8 g/cm3).
