Question

what is the unit of volume that the micropipettes described in this lab dispense?

a. nanoliters
b. milliliters
c. liters
d. microliters

clear my choice

Explanation:

Micropipettes are used to dispense very small volumes of liquid. Nanoliters are extremely small ( \(1\space nL = 10^{-9}\space L\) ), milliliters (\(1\space mL= 10^{-3}\space L\)) and liters (\(1\space L\)) are too large for the typical volumes handled by micropipettes. Microliters (\(1\space\mu L = 10^{-6}\space L\)) are the standard unit for micropipette dispensing.

Answer:

d. Microliters
