Answer : The correct option is, (B)
Solution :
According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.
or,
..........(1)
where,
= rate of effusion of unknown gas =
= rate of effusion of oxygen gas =
= molar mass of unknown gas = ?
= molar mass of oxygen gas = 32 g/mole
Now put all the given values in the above formula 1, we get:
The unknown gas could be carbon dioxide that has approximately 44 g/mole of molar mass.
Thus, the unknown gas could be carbon dioxide
