Question

Quizplus · Accepted Answer

The dilution ratio is calculated by adding the volume of the sample to the volume of the diluent and then dividing by the volume of the sample. Here, $100 \mu L + 200 \mu L = 300 \mu L$, so the dilution ratio is $300 \mu L / 100 \mu L = 3$, making it a 1:3 dilution.
