AB-016
A student was given a sample of hydrated Na2CrO4 (molar mass of anhydrous Na2CrO4.
162.0 g/mol). She determined the weight of the hydrated sample to be 2.58
heating the hydrate to drive off all the water of hydration, she determined the weight of
the anhydrous salt to be 1.77 g. Calculate the formula of the hydrated salt (round to the
nearest whole number of water molecules/mol).
After
g.

The thermogram in the figure below shows the change in mass for a sample of calcium oxalate monohydrate, CaC2O4 × H2O. The original sample weighed 42.50 mg and was heated from room temperature to1500 °C at a rate of 5 °C min. The following changes in mass and corresponding temperature ranges were observed: • Loss of 4.03 mg from 100–250 °C• Loss of 5.72 mg from 400–500 °C• Loss of 8.41 mg from 700–850 °CDetermine the identities of the volatilization products and the solid residue at each step of the thermal decomposition.

At elevated temperature NaHCO3 is quantitatively converted to Na2CO3. By calcining 0.3592 g of an antacid tablet containing NaHCO3, 0.2362 g of Na2CO3 was obtained. Calculate the percentage purity of the tablet (such as % w/w NaHCO3) It would be appreciated if you could write each step to the answer.

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.
