Verified step by step guidance1
Understand that the number 2.0 × 10^{-5} L is written in scientific notation, where the exponent indicates how many places to move the decimal point.
Since the exponent is -5, move the decimal point 5 places to the left from the number 2.0.
Start with 2.0 and move the decimal point left 5 places, adding zeros as placeholders where necessary.
After moving the decimal point 5 places left, the number becomes 0.00002 L in standard decimal notation.
Compare this result with the given options to identify the equivalent number.
