Question
A gas is found to have the formula (S2)X. It's vapour density is 128. Find the value of X :-(Molecular weight of S2 = 64)
Solution
The vapour density of a gas is defined as half of its molecular weight.
Given that the vapour density of the gas is 128, we can find the molecular weight by multiplying the vapour density by 2.
So, Molecular weight = 2 * Vapour density = 2 * 128 = 256
We know that the molecular weight of S2 is 64.
The gas has the formula (S2)X, so its molecular weight is also given by 64X.
Setting these two expressions for the molecular weight equal to each other gives us:
64X = 256
Solving for X gives us X = 256 / 64 = 4.
So, the value of X in the formula (S2)X is 4.
