Question
a mixture of NaBr & NaCl has a mass of 2g & found to contain 0.75g of Na. What is the mass of NaBr in the mixture?
Answers

NaBr = molar mass NaBr
NaCl = molar mass NaCl
Na = atomic mass Na.
Let x = NaCl
y = NaBr
--------------------\
x + y = 2
x(Na/NaCl) + y(Na/NaBr) = 0.75
Solve the two equations simultaneously fo x and y.
