Question
What is the gram molecular weight of a substance which is homoatomic molecule, when gram atomic mass is 16 and its atomicity is 2?
- 32
- 42
- 18
- 8
Hint:
Gram molecular weight is gram atomic weight multiplied by atomicity.
The correct answer is: 32
Gram atomic mass is the mass of one mole of an element. It is determined by taking the atomic weight for an element on the periodic table and expressing it in grams.
Gram molecular weight is the mass of one mole of a compound equal in grams to the molecular weight.
The gram molecular weight of a substance which is homoatomic molecule, when gram atomic mass is 16 and its atomicity is 2 is 32g.
