Question

6) How many microliter (μl) of 20% sucrose solution are required to make 2 ml of 5% sucrose solution?

Answer 1

Answer #1

Answer: 500 uL
Explanation:
Dilution principle:
C1V1 = C2V2
V1 = (C2V2)/C1

C1 = 20%
C2 = 5%
V2 = 2 mL

V1 = (C2V2)/C1
Initial volume, V1 = (5*2)/20
= 0.5 mL
= 500 uL

Please provide a positive rating. Thank you
