Asked by bilawal
A flask containing 200 mL of solution is labeled 0.300 M CuBr2. A sample containing
0.0500 moles of Br−
is added to the solution. What is the molarity of the Br−
ion solution?
Assume no volume change.
a) 0.850 M b) 0.667 M c) 1.10 M d) 1.00 M e) 0.400 M

moles br- in original solution
.5*.3*2=.3moles
adding the other moles, the moles now of Br- is .35moles
Molarity=.35moles/.2=.7M
.5*.3*2=.3moles
adding the other moles, the moles now of Br- is .35moles
Molarity=.35moles/.2=.7M
