Please don't provide handwritten solution ....

25 mL of a K₂HPO4/KH₂PO4 buffer (pKa = 6.85 for H₂PO4) with an initial pH of 7.03 was titrated with 1.0 M HCI. The buffer capacity of 25 mL of the buffer, expressed in moles of HCI consumed, is (Note: the definition of buffer capacity can be found in the introduction to Experiment 5). Use the following data to answer the question. ml HCI titrated 0 0.25 0.50 0.75 1.00 1.25 1.50 1.75 2.00 pH 7.0 6.8 6.6 6.5 6.2 5.9 4.9 2.0 1.8
