Solutions may exist as . gases, liquids,. or . solids. . . The . solute. is the . substance being dissolved. It is the gas . A Dozen Elephants & . A Dozen Paper Clips. Would a dozen of each weigh the same amount? Give a reason for your answer.. Moles and Mass. The molar mass gives us the relationship between the number of moles and the mass of an element or compound.. The Review!. (you need a periodic table, piece of scrap paper, and calculator). Review Game Rules. I will ask a question to the class.. Each participant (that’s you) . writes down. the answer silently.. By: Skye Smith. What is Mass?. Mass can be defined as a quantitative measure of an object's resistance to the change of its speed. . Scientifically speaking, mass IS different than weight, which is the measure of a planet’s gravitational force on an object. 23 . particles. . So a “mole” is a number, very similar to a dozen. . A dozen = 12 . A mole (mol) = 6.022 x 10. 23. It can be found in your reference packet on page one. Avogadro’s number = 6.022 x 10. 2. O. 3. ) . C/W. 23/09/2020. 3.2.1. Ar of Al = 27. Mass of Al in Al. 2. O. 3. = 27 x 2 = 54. Mr of Al. 2. O. 3. = (27x2) +(16x3) = 102. Percentage of aluminium = 54/102 x 100 = 52.94%. Progress Outcomes. Outline. Principles of clearance . Factors.

Solutions. In a solution, the excess material is the . solvent. , the smaller amount is the . solute. Measuring Solution Composition. Molarity is most common, covered previously in Chapter 4. Solutions are classified as mixtures.. The a. mounts of substances mixed (solute and solvent) can vary in different solutions.. Concentration. is a way of communicating how much solute is dissolved into a given amount of solution.. Molarity = moles of solute / Liters of solution. Concentration. ~How much solute is present in a solution compared to the solvent.. Molarity (M)- moles of solute per liter of solution. M = mol/L. 2.1 M AgNO. Mortar. Pestle.
