Step-by-step explanation:
We need to convert 42.0 microliters into liters. Liters and microliters are the units to find the volume. Volume is the space occupied by an object. We must know 1 micro equals to what. So,
![1\ \mu =10^(-6)](https://img.qammunity.org/2021/formulas/chemistry/high-school/28ra077ex5pekf26jggqm11j6y98d3gbpa.png)
So,
![42\ \mu L=42* 10^(-6)\ L](https://img.qammunity.org/2021/formulas/chemistry/high-school/ucyh43kw0sjo6mr8o6k6dvx70bq5bvp5fp.png)
So, there are
in 42 microliters.
