0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.
A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.
A stock solution is a concentrated solution that will be diluted to a solution of lower concentration.
stock solution = diluted solution
Where, M1 = concentration in molarity (moles/Litres) of the concentrated solution
V2 = volume of the concentrated solution,
M2 = concentration in molarity of the dilute solution
V2 = volume of the dilute solution.
The volume of 3.00M KI solution can be calculated using the dilution equation:
Given:
M1 = 3.00M, M2 = 1.25M, V1 = x, V2 = 0.300L
M1V1 = M2V2
3.00M(x) = 1.25M(0.300L)
x = 0.125L
Hence, 0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.
