Q83 of 125 Page 38

In her science class, Jyoti learned that the atomic weight of Helium is 4.0030; of Hydrogen is 1.0080; and of Oxygen is 16.0000. Find the difference between the atomic weights of:

a) Oxygen and Hydrogen


b) Oxygen and Helium


c) Helium and Hydrogen

Atomic Weight of Helium, He = 4.0030


Atomic Weight of Hydrogen, H = 1.0080



Atomic Weight of Oxygen, O = 16.0000



a) Difference between Oxygen and Hydrogen = O – H



⇒ Difference between Oxygen and Hydrogen is 14.9920


b) Difference between Oxygen and Helium = O – He



⇒ Difference between Oxygen and Helium is 11.9970


c) Difference between Helium and Hydrogen = He – H



⇒ Difference between Helium and Hydrogen is 2.9950
