Question

multiple select question select all that apply which are measurements of volume in the si system? 18.055 l 45 cm³ 22.4 μl 23.03 nm

Explanation:

Step1: Recall SI - derived unit for volume

The SI - derived unit for volume is the cubic meter ($m^{3}$). However, other commonly used volume units that are related to the SI system include cubic centimeters ($cm^{3}$), liters (L), and milliliters (mL). 1 L = 1 $dm^{3}$ and 1 mL=1 $cm^{3}$.

Step2: Analyze each option

• 23.03 nm is a unit of length (nanometer), not volume.
• 22.4 $\mu$L (microliter): 1 $\mu$L = 1 $mm^{3}$, which is a volume unit related to the SI system.
• 45 $cm^{3}$: Cubic - centimeter is a volume unit related to the SI system.
• 18.055 L: Liter is a volume unit related to the SI system.

Answer:

B. 22.4 $\mu$L, C. 45 $cm^{3}$, D. 18.055 L
