no. The water molecules linked to every molecule of

Explanation:
Mass that

Mass the

Difference in fixed of

= 19.8 - 12.6 = 7.2 g
Difference in mass synchronizes to fixed of water moved out.
Molar mass of water = 18 g/mol
No. Of moles of water =

Mass the


Mass of anhydrous

Molar massive of

No. That mol the anhydrous


so,
0.1 mol that

1 mol that


Hence, no. Of water molecules associated to each molecule that
