Mole fraction of the solute in a 1.00 molal aqueous solution is

To calculate the mole fraction of the solute in a 1.00 molal aqueous solution, we need to follow these steps:

Step 1: Understand the concept of mole fraction. Mole fraction is a way to express the concentration of a solute in a solution. It is defined as the ratio of the moles of the solute to the total moles of all components in the solution.

Step 2: Determine the moles of the solute. In this case, we have a 1.00 molal aqueous solution, which means that there is 1.00 mole of solute per kilogram of water. So, if we know the mass of water in the solution, we can calculate the moles of the solute.

Step 3: Calculate the moles of water. Since we have a 1.00 molal solution, we know that there is 1.00 mole of solute per kilogram of water. Therefore, the moles of water can be calculated by dividing the mass of water in the solution by the molar mass of water.

Step 4: Calculate the total moles of all components in the solution. To do this, we add the moles of the solute (from step 2) to the moles of water (from step 3).

Step 5: Calculate the mole fraction of the solute. The mole fraction of the solute is calculated by dividing the moles of the solute (from step 2) by the total moles of all components in the solution (from step 4).

By following these steps, you can determine the mole fraction of the solute in a 1.00 molal aqueous solution.
