which task most likely involves a calculation that uses moles?\nmeasuring a sugar sample on a balance\ncounting the number of jellybeans in a jar\ndetermining the number of atoms in a jar of liquid\nfinding the rate of expansion of a gas - filled balloon
Answer
Brief Explanations:
Moles are used to count the number of atoms, molecules or ions in a substance. Measuring sugar on a balance gives mass, counting jelly - beans is a simple count of discrete objects, and finding the rate of balloon expansion is related to volume and time. Determining the number of atoms in a jar of liquid requires using moles as a unit to convert between mass, volume and number of entities.
Answer:
determining the number of atoms in a jar of liquid
