in a classroom, which comparison would a teacher most likely use for describing a mole?\no a cup of water and a liter of oil\no a dozen eggs and a dozen jellybeans\no a jar of jellybeans and a gram of salt crystals\no 20 marbles in a bag and 10 large ice cubes
Answer
Brief Explanations:
A mole is a unit of amount of substance, similar to how a dozen represents 12 items. Just as a dozen eggs and a dozen jelly - beans both represent groups of 12 (but the items are different), a mole represents a fixed number ($6.022\times 10^{23}$) of entities (atoms, molecules, etc.). The other comparisons do not relate to the concept of a fixed - number unit like a mole.
Answer:
B. a dozen eggs and a dozen jellybeans
