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
Solution:
Atomic weight of Helium = 4.0030
Atomic weight of Hydrogen = 1.0080
Atomic weight of Oxygen = 16.0000
a. Difference between the atomic weights of Oxygen and Hydrogen
= 16.0000 - 1.0080 = 14.9920
b. Difference between atomic weights of Oxygen and Helium
= 16.0000 - 4.0030 = 11.9970
c. Difference between atomic weights of Helium and Hydrogen
= 4.0030 - 1.0080 = 2.9950
