ACS-Plus Exercise:
Scenario: You are conducting an experiment that requires a specific concentration of hydrochloric acid (HCl). You have access to a bottle of ACS-Plus HCl with a purity of 37%. You need to prepare a 1M solution of HCl.
Task: Calculate the volume of ACS-Plus HCl needed to prepare 100 ml of a 1M HCl solution.
Exercice Correction
Here's how to solve this problem: 1. **Molar mass of HCl:** The molar mass of HCl is 36.458 g/mol. 2. **Desired concentration:** You want to prepare a 1M solution, which means 1 mole of HCl per liter of solution. 3. **Mass of HCl needed:** For 100 ml (0.1 L) of a 1M solution, you need 0.1 moles of HCl. This translates to 0.1 moles * 36.458 g/mol = 3.6458 g of HCl. 4. **Volume of ACS-Plus HCl:** Since the ACS-Plus HCl is 37% pure, it means 37g of HCl are present in 100 g of the solution. You need to find the volume of this solution that contains 3.6458 g of HCl. 5. **Calculation:** Using a simple proportion: (37 g HCl / 100 g solution) = (3.6458 g HCl / X g solution). Solving for X, we get X = 9.87 g solution. 6. **Density:** Assuming the density of ACS-Plus HCl is approximately 1.19 g/ml, we can convert the mass of solution (9.87 g) to volume: 9.87 g / 1.19 g/ml = 8.3 ml. **Therefore, you would need approximately 8.3 ml of ACS-Plus HCl to prepare 100 ml of a 1M solution.**
