Question

how many atoms of phosphorus (p) are in the compound: * phosphoric acid h_{3}po_{4} 1 atom

Explanation:

Step1: Analyze the chemical formula

The chemical formula of phosphoric acid is \(H_3PO_4\). In a chemical formula, the sub - script next to an element symbol indicates the number of atoms of that element in one molecule of the compound.

Step2: Determine the number of phosphorus atoms

For the element phosphorus (\(P\)) in \(H_3PO_4\), since there is no sub - script next to \(P\), by the convention in chemical formulas (a sub - script of 1 is omitted), the number of phosphorus atoms in one molecule of \(H_3PO_4\) is 1.

Answer:

1 atom
