### Question: What is the concentration (in M) of a solution that was prepared by dissolving 31.820 g of NaOH in a 375.0 mL solution? ### Your Answer: | Answer | units | |--------|-------| | | | #### Explanation: This question asks you to calculate the molarity (M) of a solution made by dissolving a specific amount of sodium hydroxide (NaOH) in a given volume of solution. **Steps to Solve:** 1. **Calculate Moles of NaOH:** - Use the molar mass of NaOH (approximately 40.00 g/mol) to find the number of moles. - Moles of NaOH = mass (g) / molar mass (g/mol). 2. **Convert Volume to Liters:** - Since molarity is moles per liter, convert the volume from mL to L. - Volume in liters = volume in mL / 1000. 3. **Calculate Molarity:** - Molarity (M) = moles of solute / liters of solution. By following these steps, you can find the concentration of the solution in molarity (M).
