Answer:
The amount of NaOH required to prepare a solution of 2.5N NaOH.
The molecular mass of NaOH is 40.0g/mol.
Explanation:
Since,
NaOH has only one replaceable -OH group.
So, its acidity is one.
Hence,
The molecular mass of NaOH =its equivalent mass
Normality formula can be written as:
Substitute the given values in this formula to get the mass of NaOH required.

Hence, the mass of NaOH required to prepare 2.5N and 1L. solution is 100g
1 kg = 1000g
2.43 kg *1000g/1kg = 2430 g
Definite volume and indefinite shape
The ones that are known to be corrosive are PETE and PVC. These plastics you need to avoid because these are <span>plastics that can be hydrolyzed by alkaline solutions. Hope this helps on your task</span>
<span>I think There should be a valanced state in every atom. (Valanced state means, 8 electrons in the outer most orbit) In case take a atom has 8 electrons in the outer orbit, so when bonding the two atom to form a molecule, there is a Ionic Bond (because of both atoms has its own valanced electron(8 electrons in outer most orbit).</span>
