A mixture of gas "X"(mol wt. 16) and gas Y(mol wt. 28) in the mole ratio a:b has amean molecular weight 20. What would be mean molecular weight if gases are mixed in the mole ratio b:a under identacal condition (gases are non reacting).

For mixture in mole ratio a:b --> (a x 16 + b x 28) /(a+b)= 20So, 16 a + 28 b = 20 a + 20 b4a = 8b So, a = 2b, a/b = 2Now, for mole ratio b:a -->(16b + 28a)/b+a = (16 + 28a/b)/(1+a/b)Mean molecular weight = 16 + 28 x 2/1+2 = 24

Explanation:

Given Information:
- Gas X has a molar weight of 16.
- Gas Y has a molar weight of 28.
- The gases are mixed in the mole ratio a:b.
- The mean molecular weight of the mixture is 20.

Calculating the Mean Molecular Weight:
- Let the number of moles of gas X be 'a' and the number of moles of gas Y be 'b'.
- The mean molecular weight of the mixture can be calculated using the formula:
Mean molecular weight = (a*16 + b*28) / (a + b)
- Given that the mean molecular weight is 20, we can write the equation as:
20 = (16a + 28b) / (a + b)

Calculating the Mean Molecular Weight in the ratio b:a:
- If the gases are mixed in the mole ratio b:a, the new equation will be:
20 = (16b + 28a) / (a + b)
- Solving this equation will give us the mean molecular weight of the mixture when the gases are mixed in the ratio b:a.
By solving the above equation, you can find the mean molecular weight of the mixture when gases X and Y are mixed in the mole ratio b:a under identical conditions.
