2. while performing a pipetting exercise, you mix 100 μl yellow dye and 25 μl red dye in a tube. a. what is the final volume of solution in the tube in μl? b. what are the volume proportions of the two colors in the final tube?

Answer

Explanation:

Step1: Calculate final volume

Add the volumes of the two dyes. $V = 100+25=125\ \mu L$.

Step2: Calculate volume proportion of yellow dye

The proportion of yellow dye is $\frac{100}{125}=\frac{4}{5}$.

Step3: Calculate volume proportion of red dye

The proportion of red dye is $\frac{25}{125}=\frac{1}{5}$.

Answer:

a. $125\ \mu L$ b. Yellow dye: $\frac{4}{5}$, Red dye: $\frac{1}{5}$
