An oxyacid contains three hydrogen atoms, one phosphorus atom and four oxygen atoms.
Calculate the molecular masses of the salts that can be formed on reaction with NaOH

Explanation

To solve the problem of calculating the molecular masses of the salts formed from the oxyacid H₃PO₄ when it reacts with NaOH, we will follow these steps:

### Step 1: Identify the Oxyacid
The oxyacid given in the question contains 3 hydrogen atoms, 1 phosphorus atom, and 4 oxygen atoms. This corresponds to the chemical formula H₃PO₄, which is phosphoric acid.

### Step 2: Determine the Salts Formed
When H₃PO₄ reacts with NaOH, it can form three different salts:
1. Sodium dihydrogen phosphate (NaH₂PO₄)
