CHEM 107 Lecture Notes - Lecture 42: Molar Mass, Soft Drink, Molar Concentration
Document Summary
Maximum amount of solute that will dissolve at a given temperature. At the point where no more substance can dissolve. As temperature increases, solubility of solids generally increase. Solubility of a gas in a liquid increases as the pressure increases. Carbonated beverages are bottled pco2 > 1 atm. The molar mass of glycine = 75. 07 g/mol. 53. 7 g glycine x (1mol/75. 07 g) = 0. 715 mol glycine. Step 1: convert ml of solution to l. 84. 0 ml soln x (1l/1000ml) = 0. 084 l. Step 2: have molarity and volume, find moles of solute then grams of solute. 0. 500m = x mol / 0. 084 l = x = 0. 042 mol ki x 166. 01 g / 1 mol ki = 6. 97 g. If you dilute a known molar solution, the same number of particles are there, there are just fewer per unit volume. We know how to calculate the number of moles in a solution.
