First you need to find the moles of the diluted solution (moles of solute is the *same* in both concentrated and dilute solutions, so once you find moles of diluted solution you can then use this number to find the volume of the stock, or concentrated, solution). The equation for finding Molarity (M)
Na2C03 10H2O is hydrated sodium carbonate salt or sodium carbonate with water of crystallisation.
<u>Explanation</u>:
- The water atoms which are a piece of the structure of a precious stone of salt are called Water of crystallization.
The regular name and synthetic equation of an industrially significant compound which has ten water particles is Sodium Carbonate [washing soda]
Na2CO3.10H2O
Preparation:
-
A cold and Concentrated Solution of Sodium chloride is responded with Ammonia and Carbon dioxide to get Sodium Hydrogen Carbonate.
NaCl +NH3 +H2O+CO2 - >NaHCO3 +NH4Cl
-
Sodium Hydrogenarbonate is isolated by filtration, dried and warmed. On warming, sodium hydrogen carbonate deteriorates to frame Sodium carbonate.
2NaHCO3 - > Na2CO3 + CO2 + H2O
-
Anhydrous sodium carbonate is broken down in water and to get 10 atoms of water of crystallization.
Na2CO3+10H2O - >Na2CO3.10H2O
This is FALSE.
In the Bible, God created the heavens and the earth.
God said "Let there be light!" and there was.
Answer: False
