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.
The molarity (M) of a solution is calculated by dividing the moles of solute by the liters of solution:
M = mol/L
In this case, we are given the moles of sodium chloride (8.75 mol) and the volume of solution (6.22 L), so we can plug in the values:
M = 8.75 mol / 6.22 L
M = 1.41 M
Therefore, the molarity of the solution prepared by dissolving 8.75 moles of sodium chloride in enough water to produce a solution of 6.22 L is 1.41 M.
To calculate the molarity (M) of a solution, we need to use the formula:
Molarity (M) = moles of solute / volume of solution (in liters)
Given:
Moles of sodium chloride (NaCl) = 8.75 moles
Volume of solution = 6.22 L
Using the formula above, we can calculate the molarity:
Molarity (M) = 8.75 moles / 6.22 L = 1.41 M
Therefore, the molarity of the solution prepared by dissolving 8.75 moles of sodium chloride in 6.22 liters of water is 1.41 M.
