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

How many moles are in 0.50 g sodium bromide
Fiesta28 [93]
Use stoichometry to calculate this. In order to calculate this answer, you need to divide the grams by the molar mass of sodium bromide. The molar mass of sodium bromide is approximately 103 g/mol. 0.50/103 equates to about 0.00485 moles of sodium bromide.

How does an electric field change and influence its surroundings?
Maslowich

Answer:

The electric force acts over the distance separating the two objects. ... The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. A charged object creates an electric field - an alteration of the space or field in the region that surrounds it.

Answer:

Hit 10 objects and rank their sound

Explanation:

Seriously, just hit 10 objects, make your rankings of loudest to softest, then write about what materials or shapes mightve been the loudest. Im sure metal things will be loud and soft things like carpet will be quieter
