Question

33) Which contains the greatest number of moles of oxygen atoms
i) 1 mol of ethanol
ii) 1 mol of formic acid
iii) 1 mol of H²O​

Answer 1

The greatest number of moles of oxygen atoms is 1 mol of formic acid

Answer 2

Answer:

Chemical formula of the ethanol = C₂H₅OH

1 mole of the Ethanol contains 1 mole of the Oxygen atoms.

Chemical formula of the formic acid = CH₂O₂

From the formula,

1 mole of the Formic acid contains 2 mole of the Oxygen atoms. 

Chemical Formula of the Water = H₂O

From the formula, 

1 mole of the H₂O contains 1 mole of the Oxygen atoms.

Now, we can see that Formic acid contains the highest no. of the moles of the atoms.

Hence, Option (ii). is correct.
