A chemistry student must write down in her lab notebook the concentration of a solution of potassium chloride. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: - The label on the graduated cylinder says: - She put some solid potasslum chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder welghed 41.9. . - She added water to the graduated cylinder and dissolved the potassium chioride completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 177.02mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits
