Calculate the Molar Mass of the Compound

What is the molar mass of the compound dissolved in water?

Given a solution containing 11.6 g of a molecular compound dissolved in 100g of water with a boiling point of 101.5 degrees Celsius, what is the molar mass of the compound?

The molar mass of the compound is approximately 176.124 g/mol.

The molar mass of a compound can be determined by analyzing the molal concentration of the solution and the change in boiling point. In this case, the molar mass is found to be around 176.124 g/mol through a series of calculations.

To calculate the molar mass from the given data, the first step is to determine the molal concentration of the solution, which indicates the moles of solute per kilogram of solvent. Next, the moles of solute in the solution are calculated using this concentration. Finally, the molar mass is determined by considering the mass of the solute and the number of moles present.

In this scenario, the boiling point change and the knowledge that a 1 molal aqueous solution elevates the boiling point by 0.51 degrees Celsius are crucial. The molal concentration is found to be approximately 0.454 m based on the provided information. Therefore, the molar mass of the compound is determined to be around 176.124 g/mol. This calculation involves intricate steps that are essential for determining the molar mass of a compound accurately.
