1. Understand the Solution Concentration
* 23% n-butyllithium means that 23 grams of n-butyllithium are present in 100 grams of solution.
2. Calculate the Mass of Hexane
* Since the solution is 23% n-butyllithium, the remaining 77% is hexane.
* Mass of hexane = (77/100) * 100 grams = 77 grams
3. Calculate the Moles of n-butyllithium
* Molar mass of n-butyllithium (C4H9Li) = 64.06 g/mol
* Moles of n-butyllithium = (23 grams) / (64.06 g/mol) = 0.359 moles
4. Calculate the Volume of the Solution
* We need to assume a density for the solution to convert mass to volume. Since we don't have that information, we'll assume the density is close to that of hexane (~0.66 g/mL).
* Volume of solution = (100 grams) / (0.66 g/mL) = 151.5 mL = 0.1515 L
5. Calculate the Molarity
* Molarity (M) = (moles of solute) / (volume of solution in liters)
* Molarity = (0.359 moles) / (0.1515 L) = 2.37 M
Important Note: This calculation is an approximation due to the assumption about the density of the solution. The actual molarity might vary slightly depending on the precise density of the 23% n-butyllithium solution in hexane.
