In equation 4, temperature of boiling water (T1) is in the denominator.
a) If boiling temperature, recorded is too high, then denominator will be more. Then, calculated ratio will be too low.
b) If boiling temperature recorded is too low, then denominator will be less. Then, calculated ratio will be too high.

raye 2 3. You carelessly remove the stopper from Flask #1 after the water has been sucked back in and allow the water in the rubber tubing to flow into Flask #1. How does that mistake affect the calculated value of the ratio in Equation 4 (too high or too low)? Explain your answer. 4. When you determine the volume of air in Flask #1 (Steps 21 & 22), you...

actually was only 90 Celcius
Experiment 8 Questions. 1. Explain how would the calculated value of the molar mass be affected (too high, too low, no effect) if: a) the flask had been left in the water bath for so long that after all the liquid vaporized, some of the vapor escaped and was replaced by air? less...

A student following the procedure in this experiment acquired temperature as a function of time data in order to determine the heat capacity of the calorimeter. Based on a plot of these data and extrapolation back to time zero, the student determined the final temperature to be 13.6 °C The room temperature water had a volume of 48.9 mL.
