Hey guys,

I'm soo confused about the absolute uncertainties that I really am hopeless. How do you do your uncertainties for calorimetry? I have used a pipette (twice) for volume measurement, and then I used a temperature probe with additional uncertainty. But given that you multiply temperature with the mass(deriving from the volume of solutions if you are using acids and bases and you assume that they are mostly water), how do you calculate the % uncertainty? Do you add the percentages, do you multiply them or what? And also what is the absolute uncertainty? I thought that you get absolute uncertainty when you multiply the total percentage uncertainty(when you add the two percentage uncertainties) which is in form of a fraction with the actual enthalpy value that you obtain? But is this even correct? Please help me!:help:
