# 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.
