Question

A 600 mg/dL glucose solution is diluted 1:30. The concentration of the final solution in mg/dL is:

a 2
b 20
c 180
d 1,800

Answer 1

To find the concentration of the final solution, divide the initial concentration by the dilution factor. In this case, the final concentration is 20 mg/dL.

Step-by-step explanation:

To find the concentration of the final solution, we need to calculate the dilution factor. In this case, the solution is diluted 1:30, which means 1 part of the original solution is mixed with 30 parts of solvent.

So, we divide the initial concentration of 600 mg/dL by the dilution factor (30) to find the concentration of the final solution:

600 mg/dL ÷ 30 = 20 mg/dL

Therefore, the concentration of the final solution is 20 mg/dL, so the correct answer is (b) 20.
