To determine the mass of [tex]$0.359 \text{ mol}$[/tex] of potassium chloride (KCl), we can use the relationship between moles, mass, and molar mass. This relationship is given by:
[tex]\[ \text{mass} = \text{moles} \times \text{molar mass} \][/tex]
Given the information:
- Moles of KCl (\text{n}) = [tex]\(0.359 \text{ mol}\)[/tex]
- Molar mass of KCl (\text{M}) = [tex]\(74.55 \text{ g/mol}\)[/tex]
We substitute these values into the formula:
[tex]\[ \text{mass} = 0.359 \text{ mol} \times 74.55 \text{ g/mol} \][/tex]
Performing the multiplication:
[tex]\[ \text{mass} = 26.76345 \text{ g} \][/tex]
Therefore, the mass of [tex]$0.359$[/tex] mol of KCl is [tex]$ 26.76345 \text{ g} $[/tex].
