Question
Molar mass is the amount of atom present in 12gm of carbon-12 isotope. The number of particles present in one mole of the actual substance is?
- True
- False
Hint:
Molar mass of a substance is the mass in grams of one mole of the compound.
The correct answer is 'True'.
Molar mass of a substance is the mass in grams of one mole of the compound. In a substance, the amount of entities present.
In other words molar mass is the amount of atom present in 12gm of carbon-12 isotope. The number of particles present in one mole of the actual substance.
The molar mass is a bulk, not molecular, property of a substance.
