Calculate the number of moles of NaCl contained in .5000 L of a 1.5 M (Molarity) solution.

The number of moles of NaCl contained in 0.5000 L of a 1.5 M (Molarity) solution is 0.75 moles.

Explanation:

Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic, or atomic species.

Molarity M is the number of moles of solute that are dissolved in a given volume.

The Molarity of a solution is determined by the following expression:

Molarity is expressed in units .

In this case:

Reemplacing:

Solving:

number of moles of solute= 1.5 M* 0.5 L

number of moles of solute= 0.75

The number of moles of NaCl contained in 0.5000 L of a 1.5 M (Molarity) solution is 0.75 moles.

the objects have the same charge is correct.
