Homework Statement
A mixture of NaCl and NaBr has a mass of 2.08 g and is found to contain 0.76 g of Na. What is the mass of NaBr in the mixture?
Homework Equations
Molar mass equations (possibly), formula mass
The Attempt at a Solution
I've calculated the percent composition of Na in both NaCl and NaBr to be 36.22 and 63.78% respectively. With the given information I have found that sodium makes up 36.54% of the the total 2.08 g.
I am currently stuck on where to go from here since the mass of sodium in the mixture is a different percentage from an ideal mixture where it would be 28.50% of the mixture. Any help in the right direction would surely be appreciated.
