Concentrated nitric acid oxidises phosphorus to phosphoric acid according to the following equation:
`P+5HNO_(3)toH_(3)PO_(4)+H_(2)O+5NO_(2)`
What mass of phosphoric acid can be prepared from 6.2 g of phosphorus?
(H = 1, N = 14, O = 16, P = 31)

Explanation

To solve the problem of how much phosphoric acid can be prepared from 6.2 g of phosphorus, we will follow these steps:

### Step 1: Write the balanced chemical equation
The balanced chemical equation for the reaction is:
\[ \text{P} + 5 \text{HNO}_3 \rightarrow \text{H}_3\text{PO}_4 + \text{H}_2\text{O} + 5 \text{NO}_2 \]

### Step 2: Calculate the molar mass of phosphoric acid (H₃PO₄)
To find the molar mass of H₃PO₄, we add the atomic masses of all the atoms in the formula:
