Question
What is the atomicity when gram molecular weight is 18 and gram atomic weight is 9?
- 2
- 3
- 4
- 5
Hint:
Gram-atomic weight is the amount of an atomic substance whose weight, in grams, is numerically equal to the atomic weight of that substance.
The correct answer is: 2
Gram molecular weight is the mass of one mole of a compound equal in grams to the molecular weight. In other words, the gram molecular weight is the mass of a molecule in grams which is numerically equal to the molecular weight of that substance.
Gram-atomic weight is the amount of an atomic substance whose weight, in grams, is numerically equal to the atomic weight of that substance.
The atomicity when gram molecular weight is 18 and gram atomic weight is 9 is 2.
