The volume of a single tantalum atom is 1.20e-23 cm3. What is the volume of a tantalum atom in microliters?

Answer 1

1.2e-23 cm^3 = 1.2e-23 mL

10^-3 uL = 1mL

thus

1.2e-23 x 10^-3 = 1.2e-26 uL tantalum

Answer 2

Simply convert this to microliters; it is a change in the power of 10:

1 microliter = 1 x 10^-6 liters
1 liter = 10^3 cm^3
So 1 microliter = (10^-6liters)(10^3 cm^3/liter) = 10^-3 cm^3

(1.20 * 10^-23 cm^3) (1 microliter / 10^-3 cm^3) =
1.2 * 10^-20 microliters

Answer 3

Here are the conversions you can use.

A microliter is 1 x 10E-6 liters.

A cm3 = 1 mL = 1 x 10E-3 liters

So, 1.20 x 10E-23 cm3 = 1.20 x 10E-23 mL.

Now convert from mL to microliters and you are done
