A solution containing 0.8330 g of a polymer of unknown structure in 170.0 mL of an organic solvent was found to have an osmotic pressure of 5.20 mmHg at 25C. Determine the molar mass of the polymer.
Chemical Reactions: - Chemical reaction = chemical change! (conversion of one chemical substance to another via rearranging of a toms. Mass m ust be conserved) - Starting material is called a reactant - Material w e end up ith is alled a product - Types of chemical reactions: - Indications that a chemical r eaction may have o ccurred: - Change in color - Production of light - Formation of a solid (such as a precipitate in solution or a metal coating) - Formation of a gas (bubbles in
