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].

A student used 10 mL water instead of 30 mL for extraction of salt from mixture. How may this may this change the percentage of NaCI extractecd?
