Convert 0.00763 nL to L

Reptile [31]

Answer:

$7.63\cdot10^{-12} L$

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 $10^{-9}$ . In this case, we have nanoliters. Using the prefix, we can find a relationship between nanoliter and liter:

$1 nL = 10^{-9} nL$

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:

$0.00763 nL\cdot \frac{10^{-9} L}{1 nL}=7.63\cdot10^{-12} L$
