PPT-Molarity Notes Making Solutions is easy!

From Scratch Formula Sometimes you begin making a solution from solid crystal rather than diluting an already made solution This is the formula you will need Molarity moles of soluteliters of solution. B. Typical example #2: Adjustable volume, fixed weight When you weight out tiny amounts of potent and often very expensive chemicals, it is often impossible to get exactly the weight you were hoping f CllibdMli C a l at on M o l theconcentrationofchemicalsinsolution. the of solution. Thedefinitionofmolarityis: of Molarity M Molesofsolute Molarity Litersofsolution using molarity. If I have 0.075 m , . Dilution. cdurakovic@ius.edu.ba. Molarity. Molarity. is the number of moles of solute dissolved in one . liter. of solution. The units, therefore are . moles per . liter. , specifically it's moles of solute per . Reading. Skimming. involves going over a text quickly to get the general idea of its contents and to gain a superficial understanding of its message.. Scanning. involves going quickly through a text to try to find particular information or to decide whether it is useful for the reader's purpose. . Ch. . 10– . The Mole. Molarity. Concentration of a solution.. total combined volume. substance being dissolved. Molarity. 2. M HCl. What does this mean?. Molarity. . Calculations. molar mass. (. g/mol. SOLUTIONS & CONCENTRATIONS. WHAT IS A SOLUTION ?. WHAT IS CONCENTRATION & HOW IS IT MEASURED ?. IS DISSOLVING A CHEMICAL OF A PHYSICAL PROCESS ?. IF SUGAR IS DISSOLVED IN WATER IS ITS CHEMICAL NATURE CHANGED ?. Ex. 1. What is the molarity of a solution that was prepared by dissolving 11.5g of solid sodium hydroxide in 1.50L of water?. Ex. 2. Calculate the molarity of a solution prepared by dissolving 1.56g of gaseous HCl in enough water to make 26.8 mL of solution.. Calculate the molarity of a 0.175 L sugar solution that was prepared with 0.15 moles of sugar. ?. M = . mol. /L. M = 0.15 . mol. /0.175 L. M = 0.86 M. Solutions are ________________ mixtures made up of very small . If a material is pure, it consists of only a single element or compound. If the material is impure, then it is a mixture or contains two or more elements or compounds. Do not be fooled by labels that claim their product is pure… “pure 100% orange juice”. Molarity and Dilutions. E.Q.: . How is the concentration of a solution calculated . (. molarity)?. Molarity. Molarity. – . Measurement of the concentration of a solution (how much solute is in a volume of solution). . a. K. + . , . a. H. + . , a. H4SiO4. . Which chemical . concen. -. trations. from a water . analysis will give . you this information?. m. K. + . , m. H4SiO4 . , pH. Let’s review units commonly used to describe water composition at Earth’s surface.. 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. M. ). number . of . moles of solute . (n) per . liter (L). of . solution. Molarity (. M. ) = . Moles of Solute. . Liters of Solution. Note: Moles = . Mass of Solute. Molar Mass of Solute. 3.3: Molarity. Describe the fundamental properties of solutions. Calculate solution concentration using molarity. Perform dilution calculations using the dilution equation. Solutions. Remember that .
