Ok here is what I wound up with...
35gX1mole/141g=.24mole/3.5L=.068m
.0685mole/1000mlX 1 ml/1.045gX 1000g/kg=.065 mole/kg
.065moleX 141G Na2PO4/1 mole = 92.4gkg=9240ppm???
and if that is correct, then I have 18860ppm of sodium ions?
If wrong, please show me how to correct it or help me with a correct formula....
