Consider the function pH = -log[H+], where [H+] is the molarity of H+. Find [H+] and its absolute uncertainty when the pH = 4.51. The pH measurement has an absolute uncertainty of 0.05.
Perform the following calculations and determine the absolute and percent relative uncertainty. Express each answer with the correct number of significant figures. To avoid rounding errors, do not round your answers until the very end of your calculations. Perform the following calculations and determine the absolute and percent relative uncertainty.

Explain the difference between accuracy and precision. What is the difference between absolute vs. relative uncertainty? What are the equations commonly used to calculate these terms?
Absolute Error & Relative Error Absolute error: approximate value true value absolute error true value Relative error o Equivalently, approx value (true value) × (1 + rel error) o True value usually unknown, so we estimate or bound error rather than compute it exactly
1. Suppose you want to find the absolute maximum and absolute minimum values of h(x)=x-x? -9x +9 on the interval(-1,4]. What values of x would you check to find the absolute maximum and minimum? (don't find the max and min, just find the X-values you would test)
Find the absolute and relative error of the single-precision of e (Matlab:"single(exp(1))").Give at least 3 significant figures
The pH of a solution is 3.28 + or _ 0.05 what is the concentration of H+ and the absolute uncertainty. Explain
The absolute pressure at the bottom of a liquid store tank that is vented to the atmosphere is given by: Pabs,bottom = ρgh + Poutside Where: Pabs,bottom = the absolute pressure at the bottom of the storage tank (Pa)ρ = liquid density (kg/m3)g = acceleration due to gravity (m/s2)h = height of the liquid (m)Poutside = outside atmospheric pressure (Pa) Find Pabs,bottom in SI units if ρ = 1000 kg/m3, g = 32.2 ft/s2, h = 7 yd, and Poutside = 1 atm• Here are some tips to help you get started:o Remember your comment section and variable definitions o Use...
