Solutions of hydrogen in palladium may be formed by exposing Pd metal to H2 gas. The concentration of hydrogen in the palladium depends on the pressure of H2 gas applied, but in a more complex fashion than can bedescribed 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).

Question
Solutions of hydrogen in palladium may be formed by exposing Pd metal to H2 gas. The concentration of hydrogen in the palladium depends on the pressure of H2 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).
