Hello! I'm new here and I'm gonna ask some chemistry questions and I would really appreciate if you'll teach or guide me on how to solve or figure out these problems: 1. A solution is prepared by mixing 50.0 g of glucose with 600.0 g of water. What is the vapor pressure of this solution at 25°C? 2. A solution is made by mixing 50.0 g of acetone and 50.0 g of methanol. What is the vapor pressure of the solution at 25°C? What is the composition of the vapor expressed as a mole fraction? Assume ideal solution and gas behavior. 3. In a coffee-cup calorimeter, 100.0 mL of 1.0M NaOH and 100.0 mL. HCl are mixed. Both solutions were originally at 24.6°C. After the reaction, the temperature is 31.3°C. Assuming all solutions have a density of 1.0g/cm3 and a heat capacity of 4.18J/°C g, what is the enthalpy change for the neutralization of HCl by NaOH? Assume that no heat is lost to its surroundings or the calorimeter. I am not asking you to answer these questions, just reply to this post and guide me if you happen to know how to solve that, please. Thank you!
