Samples of neon gas and krypton gas are at the same temperature and pressure in a container with a small pore. In one hour, 20.0 mL of neon effuse through the pore. What volume of krypton will effuse during the same time?
A. 5.0 mL
B. 10.0 mL
C. 40.0 mL
D. 80.0 mL
Graham's law states that the diffusion or effusion of two gases at the same temperature is inversely proportional to the square root of their molar masses. Neon's molar mass is 20; Krypton's molar mass is 84. 84/20 = 4; sqrt(4) = 2. Roughly 10.0 mL,or half as much as neon, will
