**Title:** Preparation of Barium Chlorate Solution **Description:** A chemist prepares a solution of barium chlorate \((\text{Ba(ClO}_3\text{)}_2)\) by measuring out 7.47 μmol of barium chlorate into a 50. mL volumetric flask and filling the flask to the mark with water. **Objective:** Calculate the concentration in mol/L of the chemist's barium chlorate solution. Round your answer to 2 significant digits. **Diagram Explanation:** - The diagram includes a text box with a unit of concentration labeled as \( \frac{\text{mol}}{\text{L}} \). - Next to the text box, there is a numeric entry field with a multiplier selection (\(\times 10\)), allowing the user to input the concentration calculated from the problem. **Instructions:** 1. Use the given amount of barium chlorate (7.47 μmol) and the volume of the solution (50 mL) to find the concentration in mol/L. 2. Perform unit conversions as necessary to express the answer in mol/L. 3. Round the final answer to two significant digits.
