Using the periodic table, complete the following. Element: chlorine symbol: Cl_(2) Molecular weight: square g Mass of one mole: hat (a)g/mol

To complete the information for chlorine using the periodic table:<br /><br />1. **Element**: Chlorine<br />2. **Symbol**: \( Cl_{2} \)<br /><br />3. **Molecular weight**:<br /> - The atomic weight of one chlorine atom (Cl) is approximately 35.45 g/mol.<br /> - Since chlorine exists as a diatomic molecule (\( Cl_{2} \)), the molecular weight is calculated as follows:<br /> \[<br /> \text{Molecular weight of } Cl_{2} = 2 \times 35.45 \, \text{g/mol} = 70.90 \, \text{g/mol}<br /> \]<br /><br />4. **Mass of one mole**:<br /> - The mass of one mole of \( Cl_{2} \) is the same as its molecular weight.<br /> \[<br /> \text{Mass of one mole of } Cl_{2} = 70.90 \, \text{g/mol}<br /> \]<br /><br />So, the completed information is:<br /><br />- Element: Chlorine<br />- Symbol: \( Cl_{2} \)<br />- Molecular weight: 70.90 g<br />- Mass of one mole: 70.90 g/mol
