You have been given a sample of unknown molarity. Calculate the molarity of a solution which has been prepared by dissolving 8.75 moles of sodium chloride in enough water to produce a solution of 6.22l.

mols NaCl = grams/molar mass = ?

Then M = mols/L

To calculate the molarity of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters).

In this case, the amount of solute is given as 8.75 moles of sodium chloride (NaCl), and the volume of the solution is given as 6.22 liters.

Molarity (M) is defined as moles of solute per liter of solution. So, to calculate the molarity, you can use the following formula:

Molarity = moles of solute / volume of solution

Plugging in the values, you would get:

Molarity = 8.75 moles / 6.22 liters

Calculating this, you would get the molarity of the solution.
