There is a typo in the response for Molly. Molly's original volume should be written as 8.0 L, not 8 L. Apply the significant figure rule to the final answer. Your final answer should have one significant figure. Use CER, claim is your answer, evidence is your calculation, and, reasoning is your further explanation. You can provide information about the formula you used to solve as well.
a Table: (This is an example of what your data table should look like.) Pressure (kPa) Temperature (°C) Temperature (K) Constant, k(P / T or P•T) Ice water bath 91.58 2.4 275.55 Room temperature 96.54 21.1 294.25 Warm water 104.11 44.5 317.65 Boiling water 113.75 77.5 350.5 Calculations: One way to determine if a relationship is inverse or direct is to find a proportionality constant, k, from the data. If this relationship is direct, k = P/T. If it is inverse, k = P•T. Choose one of these formulas and calculate k for the pairs in your data table (divide or multiply the P and T values). Record the answers in the fourth column of the Data table. How constant were the values for k you obtained in Question 4? Good data may show some minor variation, but the values for k should be relatively constant. Comment on your calculated k values. Analysis Questions: What does temperature measure?

I need help in calculating the total mass of the unknown #2 sample of copper. The following chemical equations are in used: 2 Cu2+ + 4 I -> 2 Cus + I2 I2 + 2 S2O3-2 -> 2 I +S4O6-2 To standardize the Sodium Thiosulfate Average copper weight = 0.2536 g Average volume = 25.46 mL The Analysis of the Unknown #2 sample of copper Average mass of the unknown #2 sample of copper = 1.2474 g Average volume of sodium thiosulfate = 14.30 mL I came up with a molarity of 0.1567 for NaS2O3. Is it correct? I am coming up for the mass of the unknown #2 sample of copper: 0.1348 grams. Is that also correct?
