Question

The expression below sets up the unit conversion for this problem: 250 ml x 1000 μL/1 ml x 1 experiment/13.5 μL.

Answer 1

The question asks for a unit conversion from milliliters to microliters and then to calculate the number of experiments that can be run with the given volume. The student needs to multiply by 1000 to convert mL to µL and then divide by the volume per experiment.

Step-by-step explanation:

The student's question involves a unit conversion problem that requires converting milliliters (mL) to microliters (µL) and then determining the number of experiments that can be conducted with the converted volume. This is a common type of problem in mathematics, specifically in the area focused on units of measure and conversion factors.

To solve the problem, use the conversion factor 1 mL = 1000 µL to convert 250 mL to microliters. Then, divide the converted amount by the volume needed for one experiment (13.5 µL). The steps are:

1. Multiply the volume in milliliters (250 mL) by 1000 to convert it to microliters.
2. Divide the result by the volume needed per experiment (13.5 µL).
3. The calculation would look like this: 250 mL × 1000 µL/1 mL × 1 experiment/13.5 µL. This will give the total number of experiments that can be conducted with 250 mL of liquid.
