What volume of 0.125 M of NaI is required to make 100 mL of 0.075 M?
6 L
125 mL
60 mL
75 mL
100 mL
| a. | 6 L | |
| b. | 125 mL | |
| c. | 60 mL | |
| d. | 75 mL | |
| e. | 100 mL |
Solution
Use the formula C1V1 =C2V2
Where, C1 = initial concentration = 0..125M
V1 = initial volume = ?
C2 = final concentration = 0.075M
V2 = final volume = 100 mL
C1V1 =C2V2 Thus
V1 = C2V2 /C1
Substitute the value in above equation
V1 = 0.075 X 100/0.125 = 60 ml
Ans - c. 60 mL
