Given: 19 grams of .
To find: We have to find the number of moles.
Solution:
To determine the number of moles we have to follow the below steps-
The chemical formula of hydrogen peroxide is .
The atomic number of H is 1 and the atomic number of Oxygen is 16.
Thus the molecular weight of hydrogen peroxide is 2×1+16×2=34 grams.
34 grams of hydrogen peroxide occupy 1 mole.
So, 19 grams of hydrogen peroxide will occupy 19/35=0.54 moles.
Thus, 19 grams of will contain 0.54 moles.
