Knowing the right percent strength of a solution is important because it ensures that the solution will be effective for its intended purpose. Inaccurate percent strength can result in the solution being either too weak to be effective or too strong and potentially harmful. Proper knowledge of the percent strength also facilitates consistency and reproducibility in scientific experiments or processes.

Knowing the concentration of a solution is important because it helps determine the strength or effectiveness of the solution for a particular purpose. It also allows for accurate measurements and calculations in scientific experiments and ensures the desired outcome of a chemical reaction or process.
To determine the vapor pressure of a solution, one can use Raoult's Law, which states that the vapor pressure of a solution is directly proportional to the mole fraction of the solvent in the solution. By knowing the mole fraction of the solvent and the vapor pressure of the pure solvent, one can calculate the vapor pressure of the solution.

To determine the number of moles of solute in a solution, you can use the formula: moles mass of solute / molar mass of solute. This involves measuring the mass of the solute and knowing its molar mass, which is the mass of one mole of the substance. By dividing the mass of the solute by its molar mass, you can calculate the number of moles present in the solution.
To determine the mole fraction from vapor pressure, you can use Raoult's Law. This law states that the vapor pressure of a solution is directly proportional to the mole fraction of the solvent in the solution. By measuring the vapor pressure of the solution and knowing the vapor pressure of the pure solvent, you can calculate the mole fraction of the solvent in the solution using the formula: Mole fraction of solvent Vapor pressure of solution / Vapor pressure of pure solvent
To determine the LiOH content by titration, you would first standardize a titrant solution (e.g., HCl) of known concentration. Then, you would titrate the LiOH solution with the standardized titrant solution until the endpoint is reached (usually indicated by a color change). By knowing the volume and concentration of the titrant solution used in the titration, you can calculate the amount of LiOH present in the solution.

Ammonia is a substance that when dissolved causes a solution to be basic (pH higher than 7) however without knowing the concentration of the ammonia in solution, it is impossible to determine the pH.

To find the pH of a weak base solution, you can use the formula pH 14 - pOH, where pOH is calculated using the concentration of hydroxide ions in the solution. You can determine the concentration of hydroxide ions by knowing the initial concentration of the weak base and its equilibrium constant. By plugging these values into the formula, you can calculate the pH of the weak base solution.
To find the mole fraction of solute in a solution, you need both the moles of solute and the total moles of solute and solvent combined. In this case, the molarity of the solution (3.72 mol/L) is not enough information to determine the mole fraction without knowing the specific solute and its moles.
