1. "Diffusion" sounds slow, but on the scale of a cell it is very fast. The average instantaneous velocity of a particle in solution is v= (kT/m)", where k = 1.38 X 101 g cm?/K sec², T= temperature in K, m = mass in g/molecule. A) Calculate the instantaneous velocity of a molecule of glucose and a molecule of myoglobin (a protein), at 37°C [molecular mass for glucose = 180 g/mol; molecular mass for myoglobin = 15,000 g/mol].

You are assigned the task of separating a desired granular materialwith a density of 3.62 g/cm3 from an undesired granularmaterial that has a density of 2.04 g/cm3. You want to dothis by shaking the mixture in a liquid in which the heaviermaterial will fall to the bottom and the lighter material willfloat. A solid will float on any liquid that is more dense. Usingan Internet-based source or a handbook of chemistry, findthe densities of the following substances: carbon tetrachloride,hexane, benzene, and diiodomethane. Which of theseliquids will serve your purpose, assuming no chemical interactiontakes place between the liquid and the solids?

please use dimensional analysis with the numbers given

1.) In the Dumas method for determining the molar mass of an unknown volatile liquid, a sample of a volatile liquid that boils below 100 oC is vaporized in a boiling water bath and the mass of the vapor required to fill the flask is determined. The following data was collected:  Flask Volume 100.0 +100.0 + 79.6 mL = 279.6 mL Mass of Flask + Cap 143.85 g Mass of Flask + Condensed Liquid 144.95 g Mass of Condensed Liquid 1.10 g Temperature of Water Bath (oC)  84.1 oC Barometric Pressure (atm) 0.985 atm   a.) What is the molar mass of the unknown?  b.) What will its temperature be when the pressure is 1.20 atm and the volume is 250.0 mL?
