    Titration of unknown acid in lab, how to determine molar mass?

    No there isn't. I had 25ml of acid only. I added 7.5ml to reach equivalence point in the titration. Apparently, my V2 has to be 25ml, but I don't understand why: shouldn't the final volume should include the added NaOH volume + the acid volume (25 + 7.5) ? I'm really confused!

    Titration of unknown acid in lab, how to determine molar mass?

    OK. If I put my V2 to 25ml, it gives an answer that makes a lot of sens. However, I don't understand the logic behind it. I mean, the final volume of titration is NOT 25ml, but rather 25ml + 7.5 ml. The initial concnetration of NaOH that I have is for 7.5ml, but as we add that 7.5 to 25, it...

    Titration of unknown acid in lab, how to determine molar mass?

    Hi, Homework Statement It is in my chemistry lab course. I had 0.1g of an unknown solid that I diluted in 100ml of distilled water. Then, I took 25ml and titrated it with NaOH (Concentration = 0.0189M). To reach equivalent point (the point where concentration of NaOH is equal to the...
