Sure, here's an example of a solution practice problem:

Problem: Determine the concentration of a solution made by dissolving 25 grams of sodium chloride (NaCl) in 500 mL of water.

Solution:

Calculate the molar mass of sodium chloride (NaCl): Molar mass of NaCl = 22.99 g/mol (Na) + 35.45 g/mol (Cl) = 58.44 g/mol
Convert the mass of NaCl to moles: Mass of NaCl = 25 g Number of moles of NaCl = Mass of NaCl / Molar mass of NaCl = 25 g / 58.44 g/mol ≈ 0.428 moles
Convert the volume of water from milliliters to liters: Volume of water = 500 mL = 0.5 L
Calculate the concentration of the solution using the formula: Concentration (in moles per liter) = Number of moles of solute / Volume of solution (in liters)

Concentration = 0.428 moles / 0.5 L ≈ 0.856 moles/L

Therefore, the concentration of the solution is approximately 0.856 moles per liter.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
