In this question, we are asked to calculate the molar mass of the given gas and here we are having stp conditions.
00:08
So, temperature will be 273 .15 kelvin.
00:12
Now, the value of pressure will be 1 atm.
00:16
So, these are the conditions of stp.
00:19
So, here we can write stp and then we can say that the value of r which is the gas constant is equals to 0 .0821 and then the units will be here liter and then it is atm.
00:36
Now, here it will be mole and then it is inverse.
00:40
Now, it will be here kelvin inverse.
00:42
Hence, we can say that the value of small m will be here 0 .40 grams and now we can write that the value of here molecular mass will be, let us use the ideal gas equation in order to find out the mass of molar, we can say the molar mass of the gas...
