please give a step by step

Calculate the pH of a can of flat 7-Up. Use the average molarity of citric acid that you found in Part B. For citric acid, Ka1=7.41104, and you need only consider the first dissociation step when calculating the pH. Show your work, and circle your final answe H3C6H5O7H++H2C6H5O7 I. (from titration data) C. x+x+x E. M0x x x Would you expect the pH of carbonated 7-Up to be higher or lower than the pH you calculated in Q\#7? Explain your reasoning
