Concentrations of Solutions (Section)
Glycerol, C3H8O3, is a substance used extensively in the manufacture of cosmetics, foodstuffs, antifreeze, and plastics. Glycerol is a water-soluble liquid with a density of 1.2656 g/mL at 15 °C. Calculate the molarity of a solution of glycerol made by dissolving 50.000 mL glycerol at 15 °C in enough water to make 250.00 mL of solution.
Chapter 3 Water and Life Water supports ALL LIFE on Earth o Biological medium for life as we know it o Only common substance to exist in the natural environment in all three physical states of matter Water is a Polar Molecule o Water molecules are highly polar because oxygen atoms have much higher electronegativity than hydrogen atoms. Hydrogen and Oxygen form covalent bonds, where the electrons spend more time near the oxygen atom than the hydrogen, therefore making them Polar Covalent Bonds. This makes water a Polar Molecule o Oxygen has partial negative charge
