What is the molarity of a solution that contains 4 moles of solute and 2 liters of solution?
The molarity of the solution is 2 M.
Explanation:
Molarity (M) is defined as the number of moles of solute per liter of solution.
In this case, there are 4 moles of solute and 2 liters of solution.
So,
Molarity = moles of solute / liters of solution
Molarity = 4 moles / 2 liters
Molarity = 2 M
Therefore, the molarity of the solution is 2 M.
To calculate the molarity of a solution, divide the number of moles of solute by the volume of the solution in liters. In this case, you have 4 moles of solute and 2 liters of solution.
Molarity = moles of solute / volume of solution
Substituting the values, Molarity = 4 moles / 2 liters
Molarity = 2 moles per liter, or 2 M (Molar)
