The work has not been graded but I like the output that was submitted to me. Is it possible for the same prof to do the next assignment I will be submitting? If possible, I will greatly appreciate it.
Ariana and Alissa performed the synthesis of Ag2SO4. They measured a known mass of AgNO3, dissolved the salt in water and added this solution to an excess of aqueous K2SO4. They filtered the precipitate of silver sulfate, rinsed it with distilled water, and let it dry overnight. Next day, the mass of silver sulfate was measured. The collected results are shown in the Data Table below.
2 AgNO3(aq) + K2SO4(aq) à Ag2SO4(s) + 2 NaNO3(aq)
After doing the calculations of the theoretical yield and the percent yield, Ariana reports the % yield to be 91.0%, while Alissa claims it is 83.5%. Explain, by doing the corresponding calculations, which of the two students is correct.
Mass of watch glass
Mass of watch glass + AgNO3
Mass of beaker
Mass of beaker + Ag2SO4
