Solution :
Given :-
Volume of solution = 250ml
Conc. of solution = 0.05M
To Find :-
Mass of KOH requires to prepare require solution.
Concept :-
Molarity of solution is given by ratio of moles of solute to the volume of solution.
Mathematically,
- w denotes weight of solute
- Mw denotes molecular weight of solute
- V denotes volume of solution
Mw of KOH = 1(K)+1(O)+1(H) = 39+16+1 = 56g/mol
Calculation :-

Volume of soln=250ml=0.25 L
Molarity= 0.05 M
We know that,
molar mass of KOH =56g
