Question

If you place 2 moles of NaCL in a beaker and then add enough water to have a final volume of 0.5 liters, what is the molarity of the solution?

Answer 1

The molarity of a NaCl solution where 2 moles of NaCl are dissolved in 0.5 liters of water is 4 M (4 moles per liter).

Step-by-step explanation:

To calculate the molarity of the solution when 2 moles of NaCl are dissolved in enough water to make a final volume of 0.5 liters, you can use the formula for molarity:

Molarity (M) = moles of solute / liters of solution

In this case, the moles of NaCl (solute) are given as 2 moles, and the volume of the solution is 0.5 liters.

Thus, the molarity of the NaCl solution is:

M = 2 moles / 0.5 liters = 4 M

This means the solution's molarity is 4 moles per liter (4 M).

Answer 2

The molarity of the solution is 4M

Step-by-step explanation:

Molarity is defined as the amount of moles of solute present in one liter of solution. So the molarity of any solution can be found by dividing the moles of solute between the volume in liters of the solution.

For this case we have:

`M=(2\:moles\:NaCl)/(0.5\:L\:solution) =4M`
