How many atoms of each element (Carbon, Hydrogen and Oxygen) are in a sample of 1.202 grams of Sucrose (C12H22O11)?


There are 0.042 moles Carbon, 0.077 moles Hydrogen and 0.386 moles Oxygen in this sample.

If they already give you the amounts of moles of each element, the 1.202 g shouldn't be important. Multiply each mole amount by Avagadro's number (6.02 x 10^23 atoms/mole) to get each element's amount in atoms.

So:

Carbon: 2.5x10^22 atoms

Hydrogen: 4.6x10^22 atoms

Oxygen: 2.3x10^23 atoms

Hope this helps!
