Calculate the amount of fluorescein (MW 332.31) you will need to make 10 mL of 15 mM solution in ethanol (EtOH).

Question

My answer:0.05 g
2.Using Equation C1V1=C2V2 calculate the volume of stock solution (15 mM) you need to make 1 mL of each working solution concentration: 0 mM and 0.25 mM. Remember to convert your volumes to microliter.
My answers:
volume for 0mM --> 0 microliter
volume for 0.25 mM--> 16.67 ~ 17 microliter
3. Calculate the volume of DI H2O needed for each. Remember that this volume will be the total final volume minus the volume of stock solution you calculated.
My answers:
volume of water for the 0 mM --> 10,000 microliter subtract 0 microliter = 10,000 microliter

Answer 1

Your abbreviations are totally confusing.
I read mM as millimolarity
and I have no idea how this translates to micro in your answers.

Answer 2

I need to convert my answer (volume) into microliter.
