Calculate the number of oxygen atoms in a 120.0 g sample of glucose (c h,206). be sure your answer has a unit symbol if necessary, and round it to 4 significant digits. oro x 5 ?

Answer : The number of oxygen atoms present in glucose are

Explanation :

First we have to calculate the moles of glucose.

Molar mass of glucose = 180 g/mole

Now we have to calculate the number of oxygen atoms.

The formula of glucose is, .

In the glucose molecule, there 6 atoms of carbon, 12 atoms of hyrogen and 6 atoms of oxygen.

As, 1 mole of glucose contains number of oxygen atoms

So, 0.667 mole of glucose contains number of oxygen atoms

Therefore, the number of oxygen atoms present in glucose are
