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?

  • chem -

    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.
