Answer 2

Answer:

The molar mass of the given diatomic gas is equal to 38 grams.

Therefore, option (4) is correct.

Explanation:

Given, the mass of a diatomic gas = 9.5 g

The volume occupied by 9.5 g of gas = 5.6 L

We know that the one mole of gas occupy volume = 22.4 L

It means the mass of  22.4 L of diatomic gas will be equal to molar mass.

Now, 5.6 L of diatomic gas has mass = 9.5 g

Then 22.4 L of diatomic gas will  mass $=\frac{9.5}{5.6}\times 22.4=38 \;grams$

Therefore, the molar mass of the given diatomic gas is equal to 38 grams.
