A 4.0 mg/dl standard solution is needed.
To prepare 100 ml of the working standard,
how much stock standard of a 1-mg/ml solution is needed?
I need this one using the specific information so I understand the V1C1 = V2C2
Please explain in detail how to answer the Question. Thank you
use dilution formula
C1*V1 = C2*V2
1---> is for stock solution
2---> is for diluted solution
Given:
C1 = 1 mg/mL
C2 = 4.0 mg/dL = 4.0 mg/100 mL = 0.04 mg/mL
V2 = 100 mL
use:
C1*V1 = C2*V2
V1 = (C2 * V2) / C1
V1 = (0.04*100)/1
V1 = 4.0 mL
Answer: 4.0 mL
