Calculating the Molarity of a Solution

What is the solutions molarity?

The molarity of the solution is determined as 5.12 M.

Answer:

The molarity of a solution is calculated as follows:

Molarity is defined as the ratio of the number of moles of solute to the volume of the solution in liters.

The molarity (M) is calculated as follows:

Molarity = moles of solute / volume of solution (in liters)

Molarity = 4.28 moles / 0.836 liters = 5.12 M

Thus, the molarity of the solution is determined as 5.12 M.

Understanding Molarity in Solutions

Molarity is a key concept in chemistry that measures the concentration of a solution. It is expressed as the number of moles of solute per liter of solution. In this case, the student dissolved 4.28 moles of K3PO4 in 0.836 liters of water to produce a solution.

Molarity Calculation:

To calculate the molarity of a solution, you need to divide the number of moles of solute by the volume of the solution in liters. This calculation gives you the molarity value in moles per liter.

Formula for Molarity:

Molarity = moles of solute / volume of solution (in liters)

By plugging in the given values:

Molarity = 4.28 moles / 0.836 liters = 5.12 M

Therefore, the molarity of the solution in this case is 5.12 M, indicating a relatively high concentration of K3PO4 in the solution.
