Respuesta :
When we add water to a glass of pure fruit the volume of the solution increases while the solute remains constant so the molarity of the juice decreases.
What is Molarity ?
Molarity is defined as the amount of solute (in moles)in per litre of solution.
It is also known as molar concentration of a solution , It is expressed in mol/l .
When water is added the volume of the solution is increasing for fixed moles of juices therefore ,
The molarity of the juice will decrease and option d is correct.
