In part C of this experiment, it is possible that some of the unknown solid did not dissolve in the solvent. If this happened, after all other parts of the experiment had been done correctly, what would be the effect on the freezing point with the unknown present? How would the calculated molar mass change for the unknown solid? Specifically state whether the molar mass of the unknown would be erroneously high or erroneously low.

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
