Some Basic Concepts · Mole concept number of atoms

The correct order of total number of atoms present in
  • (A)2 moles of cyclohexane
  • (B)684 g of sucrose
  • (C)90.8 L of dihydrogen at STP
  1. (1)C >> A >> B
  2. (2)C >> B >> A
  3. (3)B >> C >> A
  4. (4)B >> A >> C
We corrected a printing error in the original paper

Answer corrected; the source key is (3) — (A) 2 mol C6_6H12_{12} = 36 mol atoms, (B) 684 g sucrose = 2 mol = 90 mol atoms, (C) 90.8 L H2_2 = 4 mol = 8 mol atoms, so B >> A >> C; also source printed “total number of atoms of present in” and option (4) “B >> A C”.
