1 IIIIIIIV II. Molarity (p ) Ch. 3 & 7 – The Mole

2 A. Molarity n Concentration of a solution. total combined volume substance being dissolved

3 A. Molarity 2M HCl What does this mean?

4 B. Molarity Calculations molar mass (g/mol) (particles/mol) MASS IN GRAMS MOLES NUMBER OF PARTICLES LITERS OF SOLUTION Molarity (mol/L)

5 B. Molarity Calculations n How many grams of NaCl are required to make 0.500L of 0.25M NaCl? L0.25 mol 1 L = 7.3 g NaCl g 1 mol

6 B. Molarity Calculations n Find the molarity of a 250 mL solution containing 10.0 g of NaF g 1 mol g = mol NaF mol 0.25 L M == 0.95M NaF
