derive the relation between volume and molecular weight of an ideal gas.
Answers
Answer:
The relationships between molar mass and density for a monoatomic gas can be easy.
The Ideal Gas Law, PV = nRT can be arranged so that n moles equals the mass/molar mass of the gas to become,
PV =
M
mRT
where m is the mass and M is the molar mass.
M =
PV
mRT
, if you hold the temperature of the gas constant the equation reduces to the Boyle's law or
PV
m
The mass will be constant assuming the container is closed and so the gas cannot be escaped so, PV will be constant.
D =
V
m
and M =
PV
mRT
M =
P
DRT
The higher the density of the gas the higher the molar mass and vice versa.

Answer:
The relationships between molar mass and density for a monoatomic gas can be easy.
The Ideal Gas Law, PV = nRT can be arranged so that n moles equals the mass/molar mass of the gas to become,
PV = MmRT
where m is the mass and M is the molar mass.
M = PVmRT, if you hold the temperature of the gas constant the equation reduces to the Boyle's law or PVm
The mass will be constant assuming the container is closed and so the gas cannot be escaped so, PV will be constant.
D = Vm and M = PVmRT
M = PDRT
The higher the density of the gas the higher the molar mass and vice versa.
