In a classroom, which comparison would a teacher most likely use for describing a mole?
a cup of water and a liter of oil
a dozen eggs and a dozen jellybeans
a jar of jellybeans and a gram of salt crystals
20 marbles in a bag and 10 large ice cubes

A dozen eggs and a dozen jellybeans.

Explanation: When there are many articles(numbers) of anything then we try to use specific unit words for these to make it easy. for example, in place of 12 inches we can say 1 feet, in place of 1000 meters we can say 1 kilometer, If we have 12 eggs or 12 bananas or jellybeans then we could use an another term dozen for this.

Similarly, when we have articles of anything then we use another term(unit) for this which is known as mole.

For example, electrons equals to 1 mole of electron.

So, the right answer is, "A dozen eggs and a dozen jellybeans."

i can ! i just need to know what the paragraph is! : p

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
