How would each of the following errors affect the determination of the molar mass of the unknown (Increase/Decrease/No effect)? a. Thermometer reads 2.0o higher than the true temperature. b. Some of the t-butanol was unknowingly spilled after it had been weighed but before the solute was added. 3. A student accidentally added acetylsalicylic acid (MW = 180.157 g/mol) rather than salicylic acid (MW = 138.121 g/mol), if no other mistakes were made, how would this error affect the determined molal freezing point depression constant for t-butyl alcohol (Kf)? 4. Based on the Tf and Kf you determined for t-butyl alcohol, predict the freezing point of a t-butyl alcohol solution containing 0.530 m NaCl. Assume 1.9 is the van’t Hoff factor for NaCl in t-butyl alcohol. Show your work.
