Chemists often use molarity M, in moles/liter, to measure the concentration of solutions Molarity is a common unt of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume Volume markings for most laboratory glassware are calibrated for room temperature, about 20°C Fortunately, there are several other ways of expressing concentration that do not involve volume and...

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...
