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

The task that is most likely involves a calculation that uses moles is that of determining the number of atoms in a jar of liquid. Calculating something which uses moles is most likely handling directly the atoms of a specific element or object.

The best answer is the third option. The task which most likely involves a calculation that uses moles is determining the number of atoms in a jar. The direct measurement we can great from the a jar is its mass. Calculating the number of atoms requires converting mass to moles and then to number of atoms.

I'm sorry i cant you if you don't list the elements : (

Anyone know the answer?
