which task most likely involves a calculation that uses moles? measuring a sugar sample on a balance counting the number of jellybeans in a jar determining the number of atoms in a jar of liquid finding the rate of expansion of a gas - filled balloon

which task most likely involves a calculation that uses moles? measuring a sugar sample on a balance counting the number of jellybeans in a jar determining the number of atoms in a jar of liquid finding the rate of expansion of a gas - filled balloon

Answer

Explanation:

Step1: Recall mole concept

The mole is a unit in chemistry used to count entities like atoms, molecules etc.

Step2: Analyze each option

Measuring sugar on a balance uses mass units (grams etc.), not moles. Counting jelly - beans is a simple count, not related to moles. Determining the number of atoms in a jar of liquid involves using Avogadro's number and moles to convert between the amount of substance and the number of atoms. Finding the rate of expansion of a gas - filled balloon is related to gas laws and volume changes, not directly to moles.

Answer:

determining the number of atoms in a jar of liquid
