PLEASE HELP FAST Valerie is preparing a blood sample for analysis. She wants to separate the solid red blood cells and obtain only the liquid portion, called plasma. The red blood cells are too small to filter out, but are denser than the plasma.

Describe the steps Valerie could take to separate the blood sample.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

Ineed ! i have no clue how to do this problem.

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.
