A 100 mL concentrated sulfuric acid (normally an Analytical Reagent, AR) will be weighed exactly to be used in a back-titration analysis. Explain how you will do this in the laboratory.
Define a function CoordTransform() that transforms the function's first two input parameters xVal and yVal into two output parameters xValNew and yValNew. The function returns void. The transformation is new = (old + 1) * 2. Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10.
Using the CelsiusToKelvin function as a guide, create a new function, changing the name to KelvinToCelsius, and modifying the function accordingly.
