Molality is used when temperature varies in an exothermic or endothermic reaction because it is not dependent on temperature or pressure.
Molality does not depend on tempratute whereas molarity does.

To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.
To convert the molality of a solution to its corresponding mole fraction, you can use the formula: Mole fraction (molality / (molality 1000)) This formula calculates the ratio of the moles of solute to the total moles of solute and solvent in the solution.

The test tube is widely used in chemistry, biology, physics to make very different experiments.
To calculate the molality of the solution, use the formula: molality (m) = moles of solute / mass of solvent in kg. Here, there are 6 moles of solute (Noah) and 3 kg of water. Thus, the molality is 6 moles / 3 kg = 2 m. Therefore, the molality of the solution is 2 m.
Molality is used for calculations instead of molarity because it is a more accurate measure of concentration. Molarity can change with temperature, while molality remains constant. This makes molality more reliable for certain calculations, especially those involving changes in temperature.
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kg. First, calculate the moles of ethanol using its molar mass and mass given, then convert the mass of water to kg. Finally, use the formula molality = moles of solute / kg of solvent to find the molality.
To calculate the molality of a solution, use the formula: molality (m) = moles of solute / mass of solvent in kilograms. Here, you have 2 moles of NaOH and 6 kg of water. Therefore, the molality is 2 moles / 6 kg = 0.33 mol/kg. Thus, the molality of the NaOH solution is 0.33 m.
John Needham failed to use properly sterilized equipment in his biology experiments, resulting in errors in his conclusion. His work was challenged by scientists who came after him.
