What is the concentration Dilution No 0000 0050 Hb stock mL

What is the concentration?

Dilution No 0.000 0.050 Hb stock (mL): Phosphate buffer (mL): 1.000 0.950 1.000 1.000 Total (mL):

Solution

Since 50 microliter is added to the 0.950 mL of phosphate buffer to make up 1.000 mL solution,

so the dilution is 1.000/0.050 = 20:1

It has the concentration of 5%.
