if thermometer is miscalibrated to read 1.0 degree celsius higher than actual temperature over its entire scale how will it affect molar mass of solute?
If you are talking about the freezing point method there will be no effect. WHY? Because the reading of the normal freezing point is 1 degree too high and the reading for the freezing point of the solution containing the solute is alo 1 degree too high; however, the DIFFERENCE reads as it should.
normal freezing point = 5.0
freezing point soln = 4.5
Difference = 5.0-4.5 = 0.5
Now suppose the thermometer reads too high by 3 degrees.
Normal freezing point = 8.0
freezing oint soln = 7.5
Difference = 8.0-7.5 = 0.5
