Answer:
2.3 * 10^-5 mL
Explanation:
The symbol " µL " stands for microliters. With respect to liters, a microliter is 10^-6 of a liter. With respect to liters, a milliliter is 10^-3 of a liter. Thus, a milliliter is 10^3 ( 1000 ) times greater than a microliter.
_______________________________________________________
Now we are asked to determine the number of milliliters given this amount of microliters. 2.3 * 10^-2 µL would have to be multiplied 10^-3 to be equal the amount of milliliters with respect to this amount of microliters,
Milliliters = 2.3 * 10^-2 * ( 10^-3 ),
Milliliters = 2.3 * 10^-5
Hope that helps!
