I was confused on this question, but I think I figured out my confusion, could someone tell me if I'm thinking about this correctly?

At first, I was confused as to why you would just calculate the number of moles of HEW. I knew that it was a 1:1 molar ratio at the equivalence point, so moles HEW = moles NAG3, and I didn't see why you couldn't just use moles of NAG3.

But then I realized that 4 equivalents of NAG3 were needed to neutralize 1 equivalent of HEW:

1*10^-3 L * .1*10^-3 mol/L HEW...
