Given below are two statements:
Statement-I : Both 12 g of carbon and 27 g of Aluminium will have (6.02 \times 10^{23}) atoms.
Statement-II : Gram atomic mass of an element contains Avogadro's no. of atoms.
In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- AStatement-I and II both are correct.
- BStatement-I is correct while II is incorrect.
- CBoth Statement-I and II are incorrect.
- DStatement-I is incorrect and II is correct.
Correct answer
A. Statement-I and II both are correct.
Step-by-step solution
Thus, Statement-I is correct because both 12 g of carbon and 27 g of aluminum correspond to 1 mole of atoms, and 1 mole contains (6.022 \times 10^{23}) atoms.
Statement-II:
"Gram atomic mass of an element contains Avogadro's number of atoms."
- The gram atomic mass (or molar mass) of an element is the mass of 1 mole of its atoms in grams, and by definition, 1 mole of any substance contains Avogadro's number ((6.022 \times 10^{23})) of atoms.
Thus, Statement-II is correct.
Conclusion:
Both Statement-I and Statement-II are correct.
