Suppose your thermometer read consistently 1.0 o C lowered throughout both parts in the colligative properties lab. What effect would that have on your experimental value for the molar mass of your unknown solute?-no effect-higher molar mass-lower molar mass
If the freezing point of the mixture had been incorrectly read 1.0 oC higher than the true freezing point, would the calculated molar mass of the solute be too high or too low? The fp of the pure substance was read correctly.
Find out the Kb of ammonia if the pH of a buffer formed by mixing 50.0 mL of 1.00 M NH 3 and 50.0 mL of 1.00 M ammonium nitrate?
Compute the final temperature of the mixture (assuming no heat loss to the surroundings). The heat capacities of H2O(s) and H2O (l) are 2.08 and 4.18 J/g · °C, respectively, enthalpy of fusion for ice = 6.02 kJ/mol.
