🤓 Based on our data, we think this question is relevant for Professor Coarfa's class at SJCD.
mass H2 = 0.94 g
mass solution = mass H2 + mass Pd
mass solution = 0.94 g + 215 g
mass solution = 215.94 g
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 (solution density = 10.8 g cm3).
(c) Determine the percent by mass of hydrogen atoms in this solution.
