Interpretation Introduction

Interpretation: The trends in abundance of the molecular ions and the ions at mass 57 and the intensities of the peaks of the mass spectrums of noctane, 3,4dimethylhexane and 2,2,3,3tetramethylbutane are to be predicted.

Concept introduction: Mass spectroscopy provides a reliable molecular weight for an unknown compound and also gives us the information about the molecular formula as well.

Fragmentation gives the resonance stabilized cations whenever possible. Loss of a small molecule is usually indicated by a fragment peak having an even mass number corresponding to loss of an even mass number.

To determine: The trends in abundance of the molecular ions and the ions at mass 57 and the intensities of the peaks of the mass spectrums of noctane, 3,4dimethylhexane and 2,2,3,3tetramethylbutane.

A 0.552-g sample of an unknown acid was dissolved in water to a total volume of 20.0 mL. This sample was titrated with 0.1103 M KOH. The equivalence point occurred at 29.42 mL base added. The pH of the solution at 10.0 mL base added was 3.72. Determine the molar mass of the acid. Determine the Ka of the acid.
