What does the chemical formula C3H6O2 tell about a molecule of the compound it represents?
2 answers:
Answer: The correct option is C.
Explanation: For a given chemical formula
3 different elements are present in this molecule that are Carbon, Hydrogen and Oxygen.
Number of Carbon atoms present = 3
Number of Hydrogen atoms = 6
Number of oxygen atoms = 2
Total number of atoms in the given molecule = 3 + 6 + 2 = 11
Hence, This molecule is made up of total 11 atoms of 3 different elements. Therefore, the correct option is C.

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
