Measurement and Matter Adding or subtracting and multiplying or dividing measurements 0/3 B 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: empty weight: 1.500 g She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 40.22 g. She added water to the graduated cylinder and dissolved the potassium chloride completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 172.08 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. A Om g·mL -1 □×1 x10 x 5

Bud N. Chemist must determine the density of a mineral sample. His four trials yield densities of 5.27 g/cm3, 5.28 g/cm3, 5.27 g/cm3, and 5.29 g/cm3. Bud's calculated average density was 5.28 g/cm3. Independent studies found the correct density to be 4.75 g/cm3. Which of the following statements represents the best analysis of the data? Bud's results have much greater accuracy than precision Bud's results have low accuracy and low precision Bud's results have high accuracy and high precision Bud's results have much greater precision than accuracy
