Question
Need to find the value of Vinf. I keep getting a small number (0.054) which doesn't work when I'm trying to find the values of the last column in the last table. (Last picture)The data is available in the picture below
The instructions to calculate Vinf is here:

Explanation / Answer
Try to follow the instructions given in the data analysis part.
It states first that weight the innitial reactant, and calculate moles. You already did that and the result is 0.01169 moles. Now convert that to moles of HCl by stechiometry:
moles of C4H9Cl = moles HCl = 0.01169 moles assuming that all the terbutyl chloride reacted (Is the limitant reactant).
Now with the acid - base titration:
HCl + NaOH --------> NaCl + H2O
moles of HCl = moles of NaOH = 0.01169 moles
We can assume this because it's a monoprotic acid and monoprotic base, and they are both strong so the rule of:
MaVa = MbVb
0.01169 = 0.04 * Vb
Vb = 0.01169 / 0.04 = 0.29225 L
Finally divided by 10 as the final step:
Vinf = 029225 / 10 = 0.029225 L or simply 29.225 mL
Now if you try this value, you should get a positive value and better results in Ln(Vinf - Vt).
Try to do this, and you'll see better results. Anything else you need, or something you think it needs to be fixed, tell me in a comment.
