A scientist has 0.46 mL of a solution. How would she convert this volume to microliters?

• chemistry -

She is a scientist and can't do that in her head? Goodness.

1mL=1000microL

• chemistry -

Go to www.google.com and type in "0.46 mL to microliters" and hit the enter button.

Don't type the quotation marks.

Relevant conversion facts:
1 mL = 0.001 L --> 1.00x10^-3 L
1 microliter = 0.000001 L --> 1.00x10^-6 L

We multiply the measurement we want to change times the appropriate labeled conversion factors. After you do units cancellations and numerical calculations, you end up with a correctly labeled answer:

(0.46mL)(0.001L/1mL)(0.000001L/1microliter)=___??

PLEASE NOTE: Every General Chemistry textbook gives examples of this formal but very useful method. It is the BEST method for converting both. simple and derived units with a built in check: If you end up with the correct units, your setup is probably correct.
