1/5 dilution of sunstance requires an additional 1/2 dilution final measurment of substances in diultion is 5.0 mg/mL. What is the concentration of the undiluted sample?
Homework Answers
First dilution = 1/5
Second dilution = 1/2
So, total dilution
= first diultion x second dilution
= 1/5 x 1/2
= 1/10
So, dilution factor = 10
Final concentration = 5.0mg/mL
Concentration of the undiluted sample
= final concentration x dilution factor
= 5.0 x 10
= 50 mg/mL
