Explanation:
Conversion problems could be solved using dimensional analysis for convenient use and understanding. Dimensional analysis is a technique of multiplying the measure we have by a fraction corresponding to some two equal measures in different units.
In order to apply dimensional analysis here, we firstly need to know that a prefix 'n' stands for 'nano', and nano means . In this case, we have nanoliters. Using the prefix, we can find a relationship between nanoliter and liter:
We may now apply dimensional analysis. Since we wish to convert into liters, we'll be multiplying the number we have in nL by a fraction that contains this relationship with liters in the numerator and nanoliters in the denominator, so that nL terms cancel out and we would obtain the final answer in liters:
