(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

Molar mass equations (possibly), formula mass

3. 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.
