➡ HERE IS YOUR ANSWER

➡ 100 ml OF AN AQUEOUS SOLUTION CONTAIN 6.023 × 10^21 MOLECULES

➡ THE SOLUTION IS DILUTED TO 1 LITRE OR 1000 ml

➡ THEREFORE, 1000 ml OF THE AQUEOUS SOLUTION CONTAINS
6.023 × 10^21 / 100 × 1000 =
6.023 × 10 ^22 MOLECULES

➡ NOW, 10 ml OF THIS SOLUTION WILL CONTAIN :-

6.023 × 10^22 / 1000 × 10 =
6.023 × 10^19 MOLECULES OF SOLUTE
