MOLARITY – Ch 13, p. 412 Quantifies the concentration of a solution.
Solution Concentration. Calculations of Solution Concentration Mole fraction Mole fraction – the ratio of moles of solute to total moles of solution.
The Arithmetic of Equations
Concentration. Concentration Particles per volume Can be in grams per litre but chemists usually express concentration in moles per litre This are related.
Solution Concentration. Calculations of Solution Concentration: Mass Percent Mass percent Mass percent is the ratio of mass units of solute to mass units.
Molarity and Molality.
Dilutions and Percent Solutions
IIIIIIIV Topic 6 The Mole I. Molar Conversions A. What is the Mole? n A counting number (like a dozen) n Avogadro’s number (N A ) n 1 mol = 6.02 10.
Molarity. Molarity Molarity (M) or molar concentration is a measure of the concentration of a solute in a solution. Unit for molar concentration is mol/L.
M OLARITY Solutions. M OLARITY (M) Is the number of moles of solute dissolved per Liter of solution. Also know as molar concentration. Unit M is read.
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.
