Question

Precisely 1 mol of helium and 1 mol of
neon are placed on a container. Indicate
the correct statements about the system
(A) Molecules of the two gases
strike the wall of the
container with same
frequency
(B) Molecules of helium strike
the wall more frequently
(C) Molecules of helium have
greater average molecular
speed
(D) Helium exerts larger pressure​

Answer 1

Answer:

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
