What is the molar mass of acetic acid by elevation of boiling point method?
The molar mass of acetic acid can be determined using the elevation of boiling point method by measuring the change in boiling point of a solution of acetic acid relative to the boiling point of the pure solvent. By applying the equation ΔT = K_b * m, where ΔT is the change in boiling point, K_b is the ebullioscopic constant of the solvent, and m is the molality of the solution, the molar mass of acetic acid can be calculated using the formula MM = (RT2) / (K_b * ΔT), where MM is the molar mass of acetic acid, R is the gas constant, and T is the temperature in Kelvin.
What are the dimensions of molar mass and how do they relate to the physical properties of a substance?
Molar mass is the mass of one mole of a substance and is expressed in grams per mole. It is a measure of the average mass of the atoms or molecules in a sample. The dimensions of molar mass are grams per mole. The molar mass of a substance affects its physical properties, such as boiling point, melting point, and density. Substances with higher molar masses tend to have higher boiling points, melting points, and densities compared to substances with lower molar masses.

What is the relationship between freezing point depression and molar mass?
The relationship between freezing point depression and molar mass is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the approximate molar mass of a molecular solute if 300 g of the solute in 1000 g of water causes the solution to have a boiling point of 101C?
The change in boiling point can be used to calculate the molality of the solution. Using that molality value, you can then calculate the moles of the solute in 300g. Finally, dividing the mass by the moles gives the molar mass, which is approximately 150 g/mol.
What substance is expected to have the highest boiling point OCl SCl2 SeCl2 TeCl2?
TeCl2 is expected to have the highest boiling point among OCl, SCl2, SeCl2, and TeCl2 because it has the largest atomic size and highest molar mass. As molecular size and molar mass increase, the van der Waals forces between molecules also increase, resulting in higher boiling points.

What is the significance of co molar mass in determining the properties of a substance?
The molar mass of a substance is important in determining its properties because it affects how the substance interacts with other substances. Substances with similar molar masses may have similar properties, such as boiling point, melting point, and solubility. This is because molar mass influences the strength of intermolecular forces between molecules, which in turn affects the substance's physical and chemical properties.
What is the relationship between the molar mass and freezing point depression in lab answers?
The relationship between molar mass and freezing point depression in lab answers is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
Why ethanol with molar mass of 46gmol boils at 78 degree Celsius than water with molar mass og 18gmol boils at 100 degree Celsius?
The boiling point of a substance depends on intermolecular forces. Ethanol has stronger intermolecular forces (hydrogen bonding) compared to water. This leads to a higher boiling point for ethanol despite its lower molar mass.
