Homework Help: Water Chemistry

Posted by Mary on Saturday, December 27, 2008 at 7:06pm.

I have a water sample that contains 0.50 mg/l (or ppm) of phosphate.
We know that phosphate is a component of Total Phosphorous.
How do I calculate what the Total Phosphorous is from my sample that contains 0.50 mg/l of phosphate???

I have to do something with the atomic weights of P and O(4)...or divide P/O(4) or 30/64 but then what???

Many thanks.
