Homework Statement We have made a standard tank in our lab. I need to calculate the uncertainty in the concentrations of the compounds we added to the tank.Homework Equations My professor indicated that I would need to use error progression to calculate an accurate uncertainty for the tank. I...

I do remember this now. Thanks, I found this earlier by playing around with the data analysis. But was looking for uncertainty when all I wanted was standard error really.

Homework Statement I need assistance in learning the proper way to calculate error/uncertainty in a few things for my undergrad thesis.Homework Equations 1) how to calculate the uncertainty in the slope and intercept of calibration curves (peak area vs mol of compound) I have made via excel...

Homework Statement solve the 2 systems x1 + 2x2 - 2x3 =1 x1 + 2x2 - 2x3 = 9 2x1 + 5x2 +x3 = 9 2x1 + 5x2 +x3 = 9 x1 + 3x2 + 4x3 = 9 x1 + 3x2 + 4x3 = -2 the question gives this explanation by doing elimination on a 3x5 augmented matrix and the performing two back...

Homework Statement I am doing an experiment to find the difference in photosynthesis between different areas of grass. I have and am taking more measurements. But essentially I need to convert the data I have into a flux per area over time. the data logger records the data of CO2...

thats what I am thinking now, that my calculations are fine, but the original measurements are wrong. Which is completely possible considering we just connected a data logger to a pressure sensor with random wire and such. I'll note it in my lab report as an error.

Homework Statement This is for a lab I finished but cannot get this question, I spoke with the TA today and she made it make sense but I am still not getting the question correct. (2) The difference in pressure between the lowest and the highest measurement point is related to the weight of...
