Answer 1

Answer:

(a)

 The gram molecular mass is the sum of the gram atomic masses.

 The gram molecular mass is the sum of the gram atomic masses.The atomic mass of H is 1 ans O is 16.

 The gram molecular mass is the sum of the gram atomic masses.The atomic mass of H is 1 ans O is 16.∴ Gram molecular mass = 2×1+16 =18g.

 The gram molecular mass is the sum of the gram atomic masses.The atomic mass of H is 1 ans O is 16.∴ Gram molecular mass = 2×1+16 =18g.(b)

 The gram molecular mass is the sum of the gram atomic masses.The atomic mass of H is 1 ans O is 16.∴ Gram molecular mass = 2×1+16 =18g.(b)Atoms are tiny particles that make up the universe, while molecules are made from atoms
