41) a student attempts to determine the formula of an unkonwn chloride sal
a) the student first takes a 9.79 g sample of the salt and fully dec
produced is 7.29 g. what is the mass of metal m contained in the salt? just
calculation to support your answer. (5 points)
te of the salt and fully decomposes it. the mass of chlorine gas
ained in the salt? justify your answer or show a brief
b) the mass of metal m collected from part a is then reacted with zinc nitrate and 6.77 zinc metal is
produced how many moles of metal m reacted? the reaction for the process is given below. (5 points)
m+zn(no3)2 → m(no3)2 + zn
c) what is the molar mass and the identity of metal m? show calculation to support your answer. (5 points)
d) what is the empirical formula of the original chloride salt in part a. justify your answer or support your
answer by calculation. (5 points)
