Molar mass of sugar = 342.3 gm

So 342.3 gm of sugar contains 11 mole of oxygen atom.

Then 50 gm of sugar will contain "\\frac{11\u00d750}{342.3}=1.6067\\ mole\\ oxygen"

Similarly,

18 gm of water contains 1 mole of oxygen atom

So, 200 gm water will contain "\\frac{1\u00d7200}{18}=11.11\\ mole \\ oxygen\\ atom"

Hence water contains the more no. of oxygen atoms
