Explain what changes and what stays the same 1.00 l of a solution of nacl is diluted to 1.80 l

Explanation:

A process in which there occurs a decrease in concentration of solute particles upon addition of more amount of solvent is known as dilution.

Also, we know that molarity is the number of moles present in a liter of solution.

Mathematically,      Molarity =

So, more is the volume of solution lesser will be the number of moles present in it. This means that when we increase the amount of solvent then there will be decrease in concentration of solute particles.

Thus, when 1.00 L of a solution of NaCl is diluted to 1.80 L then its molarity will decrease due to decrease in number of moles of NaCl.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
