**Question:** How many milliliters of an aqueous solution of 0.216 M sodium fluoride is needed to obtain 14.3 grams of the salt? [Input box for answer] - mL **Explanation:** This problem involves calculating the volume of a sodium fluoride (NaF) solution necessary to obtain a specific mass of NaF. The concentration of the solution is given in molarity (M), which is moles of solute per liter of solution. The task is to determine the volume of this solution needed to produce 14.3 grams of the salt. **Steps to Solve:** 1. Calculate the molar mass of sodium fluoride. 2. Convert the given mass of sodium fluoride into moles. 3. Use the molarity equation (moles = molarity × volume) to find the required volume in liters. 4. Convert the volume from liters to milliliters.
