P19B.4 The following data have been obtained for the adsorption of H, on the surface of 1.00 g of copper at 0°C. The volume of hydrogen has been corrected to STP (0°C and 1 atm). Assume that the Langmuir isotherm applies, calculate the volume of H,necessary to form a monolayer, and then estimate the surface area of the copper sample. The mass density of liquid hydrogen is 0.708 g cm.Hint: Use the mass density to estimate the area occupied by one H, molecule.
