Strength of a Solution
Dilute – low amount of solute dissolved in solvent Concentrated – high amount of solute dissolved
One way to measure concentration Grams of solute per Liter of solution
What is the concentration (in g/L) of a solution composed of 45g of KCl dissolved to form 1.5L of solution?
How many grams of NaOH are dissolved in 500ml of solution with a concentration of 0.75 g/L?
What volume of water is needed to form a 0.25 g/L solution if you start with 15g of CuS?
Milligrams of solute per liter of solution
What is the concentration (in ppm) of a solution made by dissolving 15g of MgO in 250ml of water?
How many grams of CaCl 2 are needed to form 200ml of a 25ppm solution?
Mass of solute/ mass of solution x 100
Find the % by mass is 25g of NaCl is dissolved in 150g of water.
What mass of water is needed to form a 15% solution starting with 20g KCl?
What mass of SrO must be dissolved in 500g of water to form a 11% solution?
1 Chapter 7 Solutions and Colloids 7.4 Solution Concentrations.
Concentration of solutions CONCENTRATED = Lots of solute in the solution DILUTE = Not much solute in the solution.
Solution Concentration Concentration – how much solute dissolved in amount of solvent Concentration – how much solute dissolved in amount of solvent what.
Molarity and Molality.
Examples-Molarity and Dilutions. Example What is the molarity of a solution that contains 4.5 moles of sucrose in L of water?
TOPIC: Concentration and Dilution Do Now:. Parts of a Solution SoluteSolute = dissolved substance SolventSolvent = dispersing medium.

Molar Concentration. Measuring Concentration Molarity (M): the number of moles of solute in 1 liter solution. Example: 0.5 moles of NaCl dissolved in.
Solution Concentration Section 14.2 Concentration - amount of solute dissolved in a specific amount of solvent concentrated - a lot of solute dilute.
Preparing a Molar Solution
DETERMING CONCENTRATIONS OF SOLUTIONS. MOLAR Molar is mol solube/1 L solution Making molar solution 1)Add ½ of the total solvent 2)Add required amount.
Concentration Concentration is the amount of solute dissolved in an amount of solution. Molar concentration is called Molarity, or M. M = moles.
Solutions: Molarity. A. Concentration – measure of the amount of solute that is dissolved in a given amount of solvent I. Concentration of Solutions Solutions:
Notes 15.2 Describing Solution Composition. Mass Percent Mass percent= mass of solute X 100 mass of solution = grams of solute X 100 grams of solute +
a measure of the amount of solute that is dissolved in a given quantity of solvent unit of measurement is Molarity (M) which is moles/liter can be dilute.
Concentration Units: Terms like “dilute” and “concentrated” are not specific. Percent by Mass: Mass % = mass of solute x 100 Total mass of solution Recall:
