A 2.158g vitamin C tablet was analyzed for ascorbic acid content. 1.785g of the tablet was used to make 100mL of solution for titration. A 25.00mL sampled of the solution required 11.85mL of 0.0982 M NaOH for neutralization. Determine the mass (in mg) of ascorbic acid in the original vitamin C tablet.
Identify the mass spectral (MS) peaks you would expect for 4-Heptanone (M+ and m/z for all fragments). Just FYI, the professor said
