PPT-Molarity

Dilution cdurakoviciuseduba Molarity Molarity is the number of moles of solute dissolved in one liter of solution The units therefore are moles per liter specifically its moles of solute per . Phys.

Molarity. = molar concentration = concentration = mole/. litre. = mol/L or M for short.. It is the number of moles per . litre. c = molar concentration in mol/L. Molarity The concentration of a solution is a measure of the amount of solute that is dissolved in a given quantity of solvent. – A dilute solution is one that contains a small amount of Chapter 7.3. Objectives. Explain the meaning of solubility and compare the solubility of various substances.. Describe dilute, concentrated, saturated, unsaturated, and super-saturated solutions.. Relate changes in temperature and pressure to changes in solubility of solid and gaseous solutes.. Ch. . 10– . The Mole. Molarity.

(tells about . the . quality, . not a #). “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 solute/liters of solution. 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). Water as a . Polar Solvent. Water is a polar molecule. since it has uneven electron distribution . and a bent molecular shape.. Due to its polar nature, water interacts strongly with its solutes and often plays an active role in aqueous reactions.. . a. K. + . , . a. H. + . , a. H4SiO4. .
