In the given question, density is given 1 .7 gram per liter.
00:08
The temperature is given 273 kelvin.
00:13
The pressure is given 1 atmosphere.
00:16
We have to find the molar mass.
00:22
The formula for density is equal to mass divided by volume.
00:28
And to solve this question, we will use ideal gas equation, which is pvegas equation, which is pve.
00:33
Pv is equal to nrt where p is the pressure, v is the volume, n is the number of moles, r is the gas constant and t is the temperature.
00:45
N number of moles can be written as mass divided by molar mass.
00:51
So we will put the value of moles in the above equation and it will become pv is equal to mrt divided by molar mass...
