Final answer:
To convert moles of NaCl to moles of Na+, simply use the 1:1 molar ratio between NaCl and Na+, as each molecule of NaCl dissociates into one Na+ ion and one Cl- ion. Thus, 0.072 mol NaCl yields 0.072 mol Na+.
Step-by-step explanation:
To convert moles of NaCl to moles of Na+, you need to consider the stoichiometry of the compound. Sodium chloride (NaCl) dissociates into one sodium ion (Na+) and one chloride ion (Cl-) when it dissolves in water.
So, if you have 0.072 mol NaCl, the conversion is straightforward:
- You already have the number of moles of NaCl (0.072 mol NaCl).
- Sodium chloride dissociates into two ions, one of which is Na+. Hence, the number of moles of Na+ ions will be the same as the number of moles of NaCl. Therefore, 0.072 mol NaCl will give you 0.072 mol Na+.
