Michelle is trying to find the average atomic mass of a sample of an unknown element. She finds that her sample contains 54.76% of an isotope with a mass of 112.3020, while the rest of the sample is an isotope with a mass of 116.8442. What is the average atomic mass of her sample? Please round your answer to 0.01 amu.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
