Determine the number of mL needed to make a solution with a certain molarity in order to create a certain number of grams of the salt.
In the lab, x grams of a compound are dissolved in water to x mL. Calculate the molarity of the solution and each ion.
The molarity and density of a compound are given, what is the percent by mass?
The mass percent and density of a compound are given, what is the molarity?
The mol frac of a compound is given. What is the percent by mass?
The mass percent and density of a solution are given. What is the mol frac?
An element is given, describe the ion: symbol, charge, name, number of electrons.
The freezing point of a liquid is given. A nonelectrolyte is dissolved (molar mass given) in x grams of the liquid to reduce the freezing point by x. There is also a table of Kb and Kf values given. How many grams were dissolved?
The boiling point of a liquid is given. A nonelectrolyte is dissolved (grams and molar mass given) in x grams of the liquid. There is also a table of Kb and Kf values given. What is the molality and what is the boiling point?
