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.

for this question, what would the correct number of significant figures be?

Which of the following are CORRECT regarding significant figures? In your answer, please list the numbers designating statements that are CORRECT. 1) when multiplying or dividing numbers, the result only has as many significant figures as the factor with the fewest significant figures- the purpose of significant figures is to indicate accuracy of a measured quantity 2) when adding or subtracting numbers, the result only has as many significant figures as the factor with the fewest significant figures 3) when adding or subtracting numbers, the result only has as many decimal places as that of the factor with the fewest decimal places 4) the purpose of significant figures is to indicate the precision of a measured quantity 5) countable quantities impact the number of significant figures in a calculation 6) when multiplying or dividing numbers, the result only has as many decimal places as that of the factor with the fewest decimal places

Solve this equation with the appropriate significant figures. 181.34 x 1930.4582 =
