A 18 g of unknown organic sample was dissolve in 756 mL of benzene. The boiling point of benzene was increased by 3.36oC. As the first step of analysis, determine the moecular weight of the unknow sample? Kb of benzene= 2.64oC/m Bb of benzene = 80.09 oC density of benzene = 0.874 g/mL at 25 °C Answer in whole number, no units required.
Based on the melting point of your impure solid, you look at the given samples and believe you havecompound A. Compound A is recrystallized using a mixed solvent system of ethanol and water. You add1 ml of hot ethanol to your sample and it doesn’t completely dissolve. You continue to add hot ethanolbut there isn’t any change. Some solid remains. What should you do next?
the pull downs are either, increase, decrease, or remain the same
