Detailed Solution
Download Solution PDF- The correct answer is option 4, i.e., 1 mole of Carbon will contain the same number of atoms as present in 1 mole of Helium.
- Out of the given options, the correct statement is: 1 mole of Carbon will contain the same number of atoms as present in 1 mole of Helium.
- A mole is the SI unit of measurement for the amount of substance.
- 1 mole = 6.022 x 1023
- 1 mole of any particle has 6.022 x 1023 of that particle. For eg: 1 mole of atom = 6.022 x 1023 atoms, 1 mole of molecule = 6.022 x 1023 molecule, etc.
- 6.022 x 1023 is known as the Avagadro number.
- A mole does not depend on the atomic number, it's just a unit.
- Thus, 1 mole of Carbon and 1 mole of Helium will contain the same number of atoms i.e. 6.022 x 1023 atoms.
