Student a performed gravimetric analysis for sulfate in her unknown using the same procedures we did . results of her three trials were 68.6%, 66.2% and 67.1% sulfate. student b analyzed the same unknown his results were 66.7%, 66.6% and 66.5%. the unknown was sodium sulfate. calculate a percent e rror fo r student a and for student b using as the accepted value the theoretical value for sulfate in sodium sulfate based on molar mass . [y ou may use the internet, a textbook, the chemistry c ommunity learning center (cclc) or any other resource for an explanation/description of percent error .] which student , a or b, was more accurate? which student was more precise? explain your answers
