To determine the mass of [tex]\(0.359\)[/tex] moles of potassium chloride (KCl), we use the molar mass of KCl as a conversion factor. Here are the steps for the calculation:
1. Identify the given information:
- Number of moles of KCl: [tex]\(0.359\)[/tex] mol
- Molar mass of KCl: [tex]\(74.55 \, \text{g/mol}\)[/tex]
2. Set up the calculation using the formula:
[tex]\[
\text{mass} = \text{moles} \times \text{molar mass}
\][/tex]
- In this case:
[tex]\[
\text{mass}_{\text{KCl}} = 0.359 \, \text{mol} \times 74.55 \, \text{g/mol}
\][/tex]
3. Perform the multiplication to find the mass:
[tex]\[
\text{mass}_{\text{KCl}} = 0.359 \times 74.55
\][/tex]
4. Calculate the result:
[tex]\[
\text{mass}_{\text{KCl}} = 26.76345 \, \text{g}
\][/tex]
Therefore, the mass of [tex]\(0.359\)[/tex] moles of potassium chloride (KCl) is [tex]\(26.76345\)[/tex] grams.
