Question

a microliter corresponds to: 10⁻² liters. 10⁻³ liters. 10⁻⁶ liters. 10⁻⁹ liters. 10⁻¹² liters.

Explanation:

Step1: Recall metric prefixes

The prefix "micro-" in the metric system represents a factor of $10^{-6}$. So, 1 microliter (μL) is equal to $10^{-6}$ liters.

Step2: Match with options

We check the options. The option with $10^{-6}$ liters is the one that corresponds to a microliter.

Answer:

$10^{-6}$ liters (the option labeled "10⁻⁶ liters")
