A chemistry student must write down in her lab notebook the concentration of a solution of sodium thiosulfate. 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: 6.2 g • She put some solid sodium thiosulfate into the graduated cylinder and weighed it. With the sodium thiosulfate added, the cylinder weighed 69.16 g. • She added water to the graduated cylinder and dissolved the sodium thiosulfate completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 176.4 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits.

A chemistry student must write down in her lab notebook the concentration
of a solution of sodium thiosulfate. 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: 6.2 g
• She put some solid sodium thiosulfate into the graduated cylinder and
weighed it. With the sodium thiosulfate added, the cylinder weighed
69.16 g.
• She added water to the graduated cylinder and dissolved the sodium
thiosulfate completely. Then she read the total volume of the solution
from the markings on the graduated cylinder. The total volume of the
solution was 176.4 mL.
What concentration should the student write down in her lab notebook? Be
sure your answer has the correct number of significant digits.
