Homework Statement
A solution is found to be 0.0330% by weight AlBr3. What is the concentration of the Br1- ion expressed in ppm?
Homework Equations
The Attempt at a Solution
Assume .0330 % => .0330 g AlBr3
.0330 g AlBr3*(1 mol AlBr3/266.697 g AlBr3)*(3 mol Br^-1 /1 mol AlBr3) =.0003712 mol Br^-1
10^6 g sol'n *(1 mL/1.0 g sol'n)*(1 L/1000^3) = 1000 L
(.0003712 mol Br^-1) /(1000 L) = 3.712*10^-6
