Thank you for your response! Having all of these numbers confused me. So for part a I'm multiplying 7.410 mL (first equivalence point) by .1523 M. I got 1.129 mmol H3PO4. Then divided it by 10.0mL to get a concentration of 0.113 M H3PO4.

i believe it wants it drawn out in a lewis structure for the product

H3C+ yes that's what the problem says

thank you. but when the question asks me to draw out the product am I drawing two structures or one?

for instance would i draw something like this? the diagonal lines are suppose to be straight lines. H-C-H / H-N-H / H
