Answer the following questions as true or false: The rate of diffusion of a gas

Question

Answer the following questions as true or false: The rate of diffusion of a gas is directly Proportion to its molar mass At a temperature of absolute zero the volume of an ideal gas Real gases behave ideally under low pressure and high temperature if the atmospheric pressure in Denver is 0.68 atm then what is this mmHg (1atm = 760 mmHg)? Convert 3K temperature to celsius temperature. A flask with a volume of 3.26 L contains 7.33 grams of an unknown gas at 380 degree C and 1.00 is the molar mass of the gas (R = 0.08206 L middot atm/K middot mol)? Arrange the following gases in order of increasing rate of effusion: C_2H_6, Ar, HCI, and PH Page 1

Explanation / Answer

Q1.

rate of diffusion of agas is propoertional to its mass, due to its size, so this is TRUE

Q2

At T = 0K, the volume of an ideal gas is INFINITE, therefore this is FALSE

Q3

Real gases behave ideal at low P and high T; this is TRUE
