75 g of sodium hydroxide is present in the solution.
<u>
</u><u>Explanation</u><u>
:</u>
Given
:
Molarity of sodium hydroxide solution= 2.5 M
Litres of Solution = 750 mL
Molar mass of NaOH = 40 g/mol
To Find:
Grams of Sodium Hydroxide =?
Solution
:
Molarity of the solution is expressed in Litres, So Converting 750.0 mL to Litres we have
750.0mL=0.750 Litres
Grams of Solution
, moles= ![M\times L](https://tex.z-dn.net/?f=M%5Ctimes%20L)
Where
M = Molarity
L = litres of solution
mol= moles of solute
![mol= 2.5 \times \frac{750}{1000}](https://tex.z-dn.net/?f=mol%3D%202.5%20%5Ctimes%20%5Cfrac%7B750%7D%7B1000%7D)
Mol = 1.875
Also the molecular weight of NaOH is 40.00 g/mol
Grams of sodium hydroxide = 1.875 mol * 40.00 g/mol = 75 g
Solutions are homogeneous mixtures made up of two non-reacting compounds. The component which is present in large quantity is called as solvent and the component in small quantity is called as solute There are six types of solutions.
1. Gas (solvent) - Gas (solute) Example= Air
2. Liquid (solvent) - Gas (solute) Example= Fizzy Drinks
3. Liquid (solvent) - Liquid (solute) Example= 96% Ethanol in Water
4. Liquid (solvent) - Solid (solute) Example= Sugar in Tea
5. Solid (solvent) - Solid (solute) Example= Brass, 18 caret Gold
6. Solid (solvent) - Gas (solute) Example= Marshmellow
Result:
In equation earth air is solvent (as it is in large quantity) and water vapors (gas) which are in small quantity is solute.
So, it is Gas - Gas Solution.
