How many grams are needed to make x mL of an x M solution?
Your numbers will vary.
A molar mass is given. Determine the osmotic pressure in mm Hg for a sample at x °C, x grams and x mL.
Your numbers will vary.
Choose all that apply. A liquid’s vapor pressure (in mmHg)at a temperature (K) is given. The compound is placed in a container (mL) and put at a certain pressure (mmHg). If the container is reduced to a new mL, what happens?
Your numbers will vary.
Rank the given substances from highest to lowest boiling OR melting point. This solver works for both. You are given molality and formulas for four compounds.

A solution is made by dissolving x grams of a substance to make x mL of solution. What is the molarity?
Your numbers will vary.
In the lab a student finds a solution with x mL of water contains x grams of a compound. Osmotic pressure (mm Hg) and temperature (K) are also given. Determine the molar mass.
Your numbers will vary.
A compound is given. X grams of the substance are dissolved in X mL of water. Density and vapor pressure of water are given. What is the vapor pressure of the solution?
Your numbers will vary.
Two temperatures (in °C) and two pressures are given. Determine the enthalpy of vaporization (ΔHvap).
Your numbers will vary.
The enthalpy of vaporization and normal boiling point are given. Determine how many kJ of heat (ΔH) are needed to evaporate or condense x kilograms. This solver works for both questions asking for evaporate the sample and questions asking to condense the sample.
