How can one determine the molar mass from molality?
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.
How can the molality of a solution be converted to its corresponding mole fraction?
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.
How do you say you like biology because its fun and you do experiments?
you feel engaged in biology, entertained, attractive, or appealing to you
What use can you make out of these tubes - glass tubing?
The test tube is widely used in chemistry, biology, physics to make very different experiments.
Why do we have to use molality for our calculations, instead of the more common unit of molarity?
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.
What is the molality of ethanol in a solution made by dissolving 14.6 g in 53.6 g of water?
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.
What did needham do wrong?
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.

What is the use of a glass plate in laboratories?
On a glass plate chemistry experiments can be performed on very small scale.In medicine and biology the glass plate can be used as support for samples.
What do chemists and biologists have in common?
Biology and chemistry are sciences based on evidence and experiments in laboratories.
