\( 82.00 \, \text{g/mol} \)

Explicar

## Step 1: <br />Identify the elements in the compound \( H_{3}PO_{3} \). The compound consists of hydrogen (H), phosphorus (P), and oxygen (O).<br /><br />## Step 2: <br />Find the atomic masses of each element from the periodic table. The atomic masses are approximately:<br />- Hydrogen (H): 1.01 g/mol<br />- Phosphorus (P): 30.97 g/mol<br />- Oxygen (O): 16.00 g/mol<br /><br />## Step 3: <br />Calculate the molar mass of \( H_{3}PO_{3} \) by summing the masses of all atoms in the formula:<br />\[ \text{Molar mass} = (3 \times 1.01 \, \text{g/mol}) + (1 \times 30.97 \, \text{g/mol}) + (3 \times 16.00 \, \text{g/mol}) \]<br /><br />## Step 4: <br />Perform the calculations:<br />\[ \text{Molar mass} = 3.03 \, \text{g/mol} + 30.97 \, \text{g/mol} + 48.00 \, \text{g/mol} \]<br />\[ \text{Molar mass} = 82.00 \, \text{g/mol} \]
