In Part A, you explored the relationship between molarity, the number of moles, and solution volume. However, when you prepare a solution, you are unable to directly measure the number of moles of solute. Instead, you can mass the solute and convert between the number of moles and mass using the molar mass of a substance as a conversion factor. The molar mass of a substance can be calculated based on its molecular formula; otherwise, it can be calculated from...

What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...

The mass of a solute versus the volume of a solution is known as mass/volume percent. It is a unit for concentration (g/L x 100%) often used in medicine, particularly with intravenous (IV) bags. If the mass percent of the saline is 0.9%, how many grams of “salt” are in a 1 L saline IV solution? Show your calculations. Retain all units where appropriate in your calculations. [HINT: 1% is the same as 1 gram in 100ml.]
