solution 2 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 3. Then 50mL of solution 3 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 4. Find the concetrations of each solution. Information of stock solution - molar mass- 534.3g/mole 0.587g in MilliQ
50 mL of stock solution were taken and added to flask. Then 50 mL of Di water were added to the flask. This is solution 1. Then 50mL of solution 1 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 2. Then 50mL of solution 2 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 3. Then 50mL of solution 3 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 4. Find the concetrations of each solution.
Information of stock solution -
molar mass- 534.3g/mole
0.587g in MilliQ
To calculate concentration of each solution, at first let us calculate the concentration in terms of molarity of the stock solution.
So, here the formula of molarity (M) as:
M = Weight of solute X 1000 / Molar mass of solute X Volume of solution in ml.
Weight of solute = 0.587 g
Molar mass = 534.3 g /mole
Volume of solution = 50 ml.
Now, put these values in above formula to calculate molartiy of stock solution.
M = 0.587 X 1000 / 534.3 X 50
= 587 / 26715
= 0.022 mol / L.
Now calculating the molarity of four stock solution by using the formula molarity of dilution as,
M1 X V1 = M2 X V2
Here,
M1 = Initial molarity
V1 = Initial volume
M2 = Final volume
V2 = Final volume.
