You are studying the boiling points of liquids with some fellow students. You have two liquids of different molecular weights, and you test each of them twice you find that the one with a lower molecular weight also has a lower boiling point would like to be more confident with the pattern you are noticing What are two possible next steps ? In one to two sentences give specific different examples of how the experiment could be extended assessed or improved?

Percent Error = | experimental value - known value | x 100% known value Screen Reader Note: To calculate percent error, find the absolute value of the difference between experimental value and known value. Take this and divide it the known value. After that, multiply by 100 %. End of note. Given the known heat of vaporization (delta H vap) of water is 44.01 kJ/mole, find the percent error using the experimentally determined delta H vap of 49.76 kJ/mole. Express with units of % in the units box.
