What is molarity?
Think about how molarity relates to the volume of the solution.
Calculate the molarity of a solution with 2 moles of solute in 4 liters of solution.
Use the formula for molarity.
What is the definition of molarity?
Think about what is being measured in chemistry.
True or False: Molality is dependent on temperature.
Consider what changes with temperature.
A laboratory measures a salt solution's density as 1.20 g/mL. You have 0.25 mol of NaCl and need to prepare 1 L. Calculate how many grams of NaCl are required.
Remember the relationship between moles and mass.
You have 50 g of NaCl and want a 2% w/w solution. How much total solution can you prepare?
Percent concentration can guide how much total mass you can achieve.
