gas a diffuses 0.75 time's as fast as gas b the mass of gas b is 32.0 g what is the mass of gas a
A sample of neon gas diffuses through a porous barrier at a rate of 89 grams per hour (g/hr). At what rate (in the same units) does it take argon gas to diffuses through the same barrier if the temperature is the same?
2.15 g of a gas occupies 0.75 L at STP. What is the molar mass of the gas? 70.1 O 64.2 O 75.0 O 3.07 x 10(-2)
A sample of neon gas diffuses through a porous barrier at a rate of 48.7 grams per hour (g/hr). At what rate (in the same units) does argon gas diffuse through the same barrier if the temperature is the same? Enter your answer in decimal form with the correct number of sig figs.
MASS TRANSFER III. A solute diffuses through a membrane that separates two compartments A and B that have different initial concentrations. The solute concentrations in the two compartments as a function of time, CA and CB are shown in Figure III-. The volumes of the two compartments are VA and (A) VA< VB (B) Solute diffuses from compartment B to A. c. Only B is true d. A and B are false a. A and B are true b. Only...
