Concentration of Solutions

Unit 10B Review Reg Chem When a solution sits out over a long period of time and water evaporates the concentration of the solution __________.

Stoichiometry Stoichiometry CDO High School. Stoichiometry Consider the chemical equation: 4NH 3 + 5O 2  6H 2 O + 4NO There are several numbers involved.

Monday March 16, 2015 Mrs. Schultz Chemistry & Integrated Science.

Solution types of stoichiometry problems are no harder than any other stoichiometry problem. You must use the concentration given (molarity) to convert.

1 Molarity. 2 Review of Converstions Fractions that = 1 Different units and numbers that equal each other Example: 1 in. = 2.54 cm Factors: 1 in. OR 2.54.

Moles in Solution A solution consists of a solvent with a solute dissolved in it The concentration of a solutions tells us how much solute is present in.

% by Mass Another way to measure the concentration of a solution % by mass = mass solute x 100 mass solution Solution = solute + solvent.

The Mole: A Measurement of Matter Describe how Avogadro’s number is related to a mole of any substance Solve problems involving mass in grams, amount in.

Molar Mass & Percent Composition. The mass of 1 mole of an element or compound – The mass in grams from the Periodic Table Unit = grams per mole (g/mol)
