A solution is prepared by mixing 90.0 mL of 5.00 M HCl and 30.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H_], , and the pH for this solution.
Chapter 13: HNMR and CNMR guide Here I’d like to give my method on solving NMR questions. I find it easier to go through all NMR questions in a similar approach. You don’t have to use this approach, and you don’t have to go in the specific order, and you can even combine all the steps, but it provides a good flowchart of the things to look for when you are given an NMR. Step 1: Calculate the degrees of freedom! The degrees of freedom are very helpful in trying to piece together the structure of the compound. To calculate the degrees of freedom, use the following formula: For example, to find the degrees of freedom for the structure above, [(7 x 2) + 2 + 1 – 6 – 1]/2 = 5 Below I’ve written a list of the common usages of degrees of freedom
