Question 3 (1 point)
A sodium bromide solution containing $3.0 \mathrm{~g}$ of sodium bromide is reacted with excess dimercury (I) acetate solution given the following reaction:
NaBr(aq)+HgCH₃ COO(aq) →NaCH₃COO(aq)+HgBr(s)
The mass of the dry precipitate is measured to be 4.000g. Calculate the percent yield for the precipitate.
Round to the nearest whole number. Your answer may be greater than 100 %. Identification of compound is not necessary.
