Hi,
I am trying to figure out how to calculate the average temperature of 2 different chemical solutions based upon the temperatures I measured. The question states: Find the average Ti of HCl & NaOH solutions.
The Ti of NaOH solution is: 20.87 C
The Ti of HCl solution is: 21.16 C
Do I just add the 2 temperatures and divide by 2, like so: 20.87 + 21.16=43.03, 43.03/2 = 21.15 ?
Yes, that's how you do in concept b ut not with those numbers. When I add them i get 42.03 and that divided by 2 is not 21.15.
Thank you very much, Dr.Bob! You are correct, I accidentally added the values incorrectly. We conducted the lab in class, which is where I measured the temperature for both solutions and obtained the Ti shown above. I just wanted to make sure that there wasn't some kind of formula for calculating the average of Ti. The solution seemed too easy!
Thanks!
To find the average temperature of two different chemical solutions based on the temperatures you measured, you will indeed add the two temperatures together and then divide by the number of measurements.
In this case, you measured two temperatures: 20.87°C for the NaOH solution and 21.16°C for the HCl solution.
So, to calculate the average temperature (Ti), you would add the two temperatures together: 20.87 + 21.16 = 42.03.
Next, divide the sum by 2 (since there are two measurements): 42.03 / 2 = 21.015.
Rounding to the nearest hundredth, the average Ti of the HCl and NaOH solutions is approximately 21.02°C.
To calculate the average temperature of two different chemical solutions, you need to sum the temperatures of the solutions and then divide by the number of solutions. In this case, you have two solutions, HCl and NaOH.
To find the average temperature, you would add the temperatures of the two solutions together and then divide the sum by 2 (the number of solutions).
For example:
Ti_average = (Ti_HCl + Ti_NaOH) / 2
Substituting the given values:
Ti_average = (21.16 + 20.87) / 2
Ti_average = 42.03 / 2
Ti_average = 21.015°C
So, the average Ti of HCl and NaOH solutions is approximately 21.015°C.
