C1V1 = C2V2
C1 = 10 mM
V1 = ?
C2 = 3 mM
C2 = 10 mL
10 × V1 = 3 × 1
V1 = 0.3 mL = 300 uL
We need 300 uL of stock and (1000 - 300 = 700 uL) of water.
1 mL = 1000 uL
Please rate high.

Suppose you made the intestinal sac too small, and at the end of experiment you could collect only 100 microliters of solution instead of 200 microliters for analysis. You perform the DNS reaction with 100 ul of the recovered solution and 100 ul of water (to bring volume up to 200 ul). How that would affect the concentration of glucose you determined from the standard curve? Normal Experiment 200 ul solution 200 ul of DNS 400 ul of H2O A)Half...
