Question

Which of the following contains maximum number of atoms?

(a) 6.023 x 10²¹ molecules of CO₂

(b) 22.4 L of CO₂ at STP 

(c) 0.44 g of CO₂

(d) None of these

Answer 1

Correct option is (b) 22.4 L of CO₂ at STP

No. of atoms in (a) = 3 x 6.023 x 10²¹

No. of atoms in (b) = 3 x 6.023 x 10²³

No. of atom in (c) = (0.44/44) x (6.023 x 10²³) × 3
