Hello students, let's begin with this question.
00:03
In this question firstly the density of the unknown gas is given which is equals to 1 .95 gm per litre and in this question we have to find out the molar mass of gas.
00:21
So here so this question can be solved by applying the ideal gas equation.
00:27
So according to this equation pressure into volume is equals to number of moles into r into t.
00:33
Let's assume this to be equation 1 and the formula used to find out the number of moles is equals to given mass upon the molar mass of the substance.
00:46
So now here let's assume this to be 2.
00:50
Now here we can substitute the value of this moles is equals to mass upon molar mass in equation 1.
00:56
So pressure into volume is equals to given mass upon molar mass into r into t.
01:03
Also let's rearrange this.
01:04
So pressure into molar mass is equals to mass upon volume into r into t...
