MOLARITY – Ch 13, p. 412 Quantifies the concentration of a solution.
Molarity What is it and how is it calculated?. Molarity What is it? A measurement of a solution’s concentration How much solute is dissolved in a solvent.
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.
% by Mass Another way to measure the concentration of a solution % by mass = mass solute x 100 mass solution Solution = solute + solvent.
Molarity and Molality.
Molarity moles of solute Liters of solution Unit for molarity mole mol LiterL = M.
Molar Concentration. Measuring Concentration Molarity (M): the number of moles of solute in 1 liter solution. Example: 0.5 moles of NaCl dissolved in.
Ch. 13/14: Solutions Describing a Solution’s Composition.
IIIIIIIV C. Johannesson The Mole I. Molar Conversions.
Solutions and Concentrations Notes Page 5. SOLUTIONS A homogenous mixture of two or more substances.
One liter of 5.0 M HCl contains how many moles of HCl? M = 5.0 mol= ? L = 1 L x = 5 mol.
Concentration Units: Terms like “dilute” and “concentrated” are not specific. Percent by Mass: Mass % = mass of solute x 100 Total mass of solution Recall:
