Question

Li3PO4 W(Li)-? W(P)-? W(O)-?

Answer 1

7×3+21+16×4=21+21+64=106

21÷106×100=19.8 Li

21÷106×100=19.8 P

64÷106×100=60.32 O

Answer 2

The chemical formula for lithium phosphate is Li3PO4. In this compound, the subscript numbers indicate the number of each element present.

To determine the atomic weights (W) of the elements in lithium phosphate, we can refer to the periodic table. Here are the atomic weights:

W(Li) - Lithium (Li): Approximately 6.94 g/mol W(P) - Phosphorus (P): Approximately 30.97 g/mol W(O) - Oxygen (O): Approximately 16.00 g/mol

Please note that the atomic weights provided are approximate values as they may vary slightly depending on the isotopes of the elements.
