What is molality in science?
in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. Molality is a means of expressing the concentration of a chemical solution.

Is HgO soluble in water?
HgO is rather insoluble in water, so the above solution could not be made. of course, the point of the question is not to make the solution, it is to learn how to do molality calculations. In the molarity tutorial the phrase "of solution" kept showing up. The molarity definition is based on the volume of the solution.
Do balances give grams or moles?
Now, let's change from using moles to grams. This is much more common. After all, chemists use balances to weigh things and balances give grams, NOT moles.
Does molarity matter if it is sucrose?
Notice that no mention of a specific substance is mentioned at all. The molarity would be the same no matter what the substance. It doesn't matter if it is sucrose, sodium chloride or any other substance. One mole of anything contains 6.022 x 1023units.
Is mol/kg in italics?
A symbol for mol/kg is often used. It is a lower-case m and is often in italics, m. Some textbooks also put in a dash, like this: 1.00-m. However, if you write 1.00 m for the answer, without the italics, then that usually is correct because the context calls for a molality.
Is molality a volume?
However, the molality definition does not have a volume in it and so is independent of any temperature changes. This will make molality a very useful concentration unit in the area of colligative properties. Lastly, it is very common for students to confuse the two definitions of molarity and molality.
