Sucrose : C12 H22 O11
Molar mass : 342 gm/mole
Number of moles in 3.42 gms of Sucrose: 3.42/342 = 0.01 moles
In one molecule we have 11 oxygen atoms. In 0.01 moles we have:
11 * 0.01 * 6.022 * 10²³ atoms
In 18 gms of water H2O : we have 6.022 *10²³ atoms of Oxygen.
Total number of Oxygen atoms : 1.11 * 6.022 * 10²³
Molar mass : 342 gm/mole
