Consider the combustion reaction between 25.0 mL of liquid methanol (density = 0.850 g>mL) and 12.5 L of oxygen gas measured at STP. The products of the reaction are CO2(g) and H2O(g). Calculate the volume of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
General Chemistry Week 11 Notes Solutions: The word “liquid” is often reserved for pure substances, so solutions are considered mixtures Solvent component in larger quantity the component dissolving the solute often water Solute Component in smaller quantity the component being dissolved example: salts Molarity [M]: Short for moles/ liter Moles of solute/ final volume Abbreviated by capital M [ ] brackets indicate concentration (molarity) Concentration (weight percent) Concentration is shown as the number of grams of solute in 100 grams of solution Ex: 5% NaCl solution= 5 grams NaCl in 100 grams of solution Preparing Solutions from Solids Start with
