Help to understand the designations P-PO4.

Elizabeth882

Hello! I came across a designation, for example, P-PO4 = 0.5. What does it mean literally? How can I determine the phosphorus content from this? Or just the anion of phosphoric acid? I understand that PO4:P = 3.07, but I don't know what P-PO4 means or how to interpret it. What is the conversion order and logic? Thank you.

Thank you! I have already looked at the reference, but it only helped partially. I understand the notation P-PO4 as follows: the phosphorus content in the form of phosphate anion is equal to 0.5. Therefore, since the ratio between anions and phosphorus is 3.07, to obtain the value of phosphorus alone, do I need to multiply 0.5 by 3.07? The question is whether I am interpreting this correctly.
