Question

A 5.05g samplers a compound is dissolved in enough water to form 100.0mL of solution. This solution has an osmosis pressure of 0.03289 atm at 25 middot C. If it is assume that each molecule of solute dissociates into two participles in this solvent, what is the molar mass of the solute? Delta Hvap for water is 40.7kj/mol. Calculate the boiling point of water at 0.005 atm A 151 mL sample of O2 was collected over water at 21 middot C when the baromic pressure was 0.976atm. What mass of O2 was contained in the sample? The Vapor pressure of water at 21 middot C is 0.0246atm Calculate the amount of heat absorbed by 10.0 grams of ice at -150.0DegreeC in converting it to liquid 50.0DegreeC.
