Answer:0.01

Explanation:No. of moles of glucose= 6.02x10^20÷6.02×10^23=0.001

Volume=100 mL= 0.1 L

Molarity= no. of mol/ vol

= 0.001/0.1 = 0.01

(d) 0.01M is the best answer.

Explanation:

  • It is described because of the wide variety of moles of the solute in 1liter of the solution.
  • Number moles of the given problem is = 6.02 × 10²⁰.
  • Number of moles =  6.02 × 10²⁰/  6.02 × 10²³ = 10⁻³mol.
  • Volume of the solution =100ml =0.1L.

Therefore, we know, Molarity = number of moles/Volume = 10⁻³/0.1 = 0.01M.
