The percent concentration of a solution is a ratio of the amounts of dissolved solute and solution, expressed as a percentage. The percent concentration of a solution can be written generally as % concentration = amount of solute x 100% amount of solution Depending on the situation, a percent concentration might be calculated for mass/mass, volume/volume, or mass/volume. tab os lock ntrol esc alt option Q A Z 5,566 2 W S AUG 2 F2 X H command 3 20 E F3 D $ 4 C 888 R Part A F4 70 Calculate the mass percent of a solution that is prepared by adding 54.8 g of NaOH to 461 g of H₂O.

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].
