Report your numeric answer only and to the correct number of significant figures.Measurement and Matter Adding or subtracting and multiplying or dividing measurements 1/3 B A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. 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: 7.2 g . She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 63.517 g. . She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 91.0 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. g-mL G2.93 g Measured Volume of Water: 100.0 mL each question with correct significant figures and units.
