What happens to a glass of pure fruit juice when water is added to it?

The number of moles of fruit juice increases.
The number of moles of fruit juice decreases.
The molarity of the juice increases.
The molarity of the juice decreases.

The molarity of the juice decreases.

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

= volume of solution in L

As volume of solution is inversely proportional to molarity, as water is added to juice, the volume of solution increases and thus the molarity decreases.

The moles remain fixed on adding water to juice.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

let that person have a turn to speak : )
