A chemist has run out of table salt (NaCl) and needs 0.1 moles of it to make dinner.How many moles of chlorine does he need?0.0550.50.1Feedback?

1. Break Down the Problem

To determine how many moles of chlorine are needed, we start with the chemical formula for table salt (NaCl), which consists of one sodium atom (Na) and one chlorine atom (Cl). Therefore, 1 mole of NaCl contains 1 mole of Cl.

2. Relevant Concepts

From the formula: $\text{NaCl} \rightarrow \text{Na}^+ + \text{Cl}^-$ This equation indicates that for every mole of NaCl produced, there is 1 mole of Cl required.

3. Analysis and Detail

Given that the chemist needs 0.1 moles of NaCl:

• Since 1 mole of NaCl corresponds to 1 mole of Cl, the number of moles of Cl needed is equal to the number of moles of NaCl required.

4. Verify and Summarize

Thus: $\text{Moles of Cl} = \text{Moles of NaCl} = 0.1$ Therefore, the chemist needs 0.1 moles of chlorine.

Final Answer

The chemist needs 0.1 moles of chlorine (Cl).
