Answer : The molecular weight of a gas is, 128.9 g/mole
Explanation : Given,
Density of a gas = 5.75 g/L
First we have to calculate the moles of gas.
At STP,
As, 22.4 liter volume of gas present in 1 mole of gas
So, 1 liter volume of gas present in
mole of gas
Now we have to calculate the molecular weight of a gas.
Formula used :
![\text{Moles of gas}=\frac{\text{Mass of a gas}}{\text{Molecular weight of a gas}}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20gas%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20a%20gas%7D%7D%7B%5Ctext%7BMolecular%20weight%20of%20a%20gas%7D%7D)
Now put all the given values in this formula, we get the molecular weight of a gas.
![0.0446mole=\frac{5.75g}{\text{Molecular weight of a gas}}](https://tex.z-dn.net/?f=0.0446mole%3D%5Cfrac%7B5.75g%7D%7B%5Ctext%7BMolecular%20weight%20of%20a%20gas%7D%7D)
![\text{Molecular weight of a gas}=128.9g/mole](https://tex.z-dn.net/?f=%5Ctext%7BMolecular%20weight%20of%20a%20gas%7D%3D128.9g%2Fmole)
Therefore, the molecular weight of a gas is, 128.9 g/mole
