Narceine is a narcotic in opium that crystallizes from solution as a hydrate that contains 10.8 mass % water and has a molar mas
Leto [7]

Thewater of hydration x in narceine. xH₂O is 3

<h3>What is Water of Hydration?</h3>
  • In chemistry, water molecules found inside crystals are referred to as "water of crystallization" or "water of hydration." When crystals are formed from aqueous solutions, water is frequently included.
  • The entire mass of water in a substance at a specific temperature is sometimes referred to as water of hydration, and it is typically present in a stoichiometric ratio.
  • The term "water of crystallization" has historically been used to describe water that is not physically linked to the metal cation but is present in the crystalline structure of a metal complex or salt.
  • Many chemicals include water molecules in their crystalline structures when they crystallize from water or solvents that contain water. Heating a sample usually removes the water of crystallization, but the crystalline qualities are frequently lost.

Given that hydrate is 10.8% by mass

molar mass = 499.52 g/mol

calculating the amount of water

mass of water = \dfrac{10.8 \times 499.5}{100}

mass of water = 53.95 g

moles of water = \dfrac{mass}{molar mass}

moles of water = \dfrac{53.95}{18} = 3

then the water of hydration x in narceine. xH₂O is 3
