Type: MCQ-conceptual-Medium
Which one of the followings has maximum number of atoms?
A
1 g of Ag(s) [Atomic mass of Ag = 108]
B
1 g of Mg(s) [Atomic mass of Mg = 24]
C
1 g of O₂(g) [Atomic mass of O = 16]
D
1 g of Li(s) [Atomic mass of Ag = 7]
Correct Answer
Option D
Detailed Explanation
1 mole of a substance contains Avogadro's number of atoms. For 1 g of each substance, the number of atoms is inversely proportional to the atomic mass. Li has the smallest atomic mass, hence 1 g of Li has the maximum number of atoms.
