Q. Which one of the followings has maximum number of atoms ?
A) 1 g of Mg(s) [Atomic mass of Mg = 24]
B) 1 g of $O_2$(g) [Atomic mass of O = 16]
C) 1 g of Li(s) [Atomic mass of Li = 7]
D) 1 g of Ag(s) [Atomic mass of Ag = 108]
Explanation
[Solution] Moles of atoms: Mg 1/24, O 2/32 = 1/16, Li 1/7, Ag 1/108; Li has the most. Answer (3).
