If some of the unkown was stuck to the side of the test tube or otherwise did not dissolve completely before cooling, how would the molecular mass of the unknown obtained be affected? HINT: if it doesn't all dissolve, what will be the effect on the DT? And therefore, what will be the effect on the moles of unknown you calculate? And therefore, since you have the known mass weighed, what will happen to the molar mass? O The molar mass calculated will end up falsely high. O The molar mass calculation will not be affected. The molar mass calculated will be falsely low.
