Answer
- There are $10^6$ $µL$ in 1 L.
- There are $2.0 \times 10^4 µL$ in $20$ $mL$
Work Step by Step
$1$ $L \times \frac{1 µL}{10^{-6}L} = 10^{6}$ $µL$
- There are $10^6$ $µL$ in 1 L.
$20$ $mL \times \frac{10^{-3}L}{1mL} \times \frac{1µL}{10^{-6}L} = 2.0 \times 10^4$ $µL$
- There are $2.0 \times 10^4 µL$ in $20$ $mL$
