The structure of the ion at m/z 304 and 182 has to be drawn. Concept Introduction: Mass spectrometry is an analytical tool that determines the mass to charge ratio of molecular ion. When solid, liquid, and gaseous substances are bombarded with high energy electrons, they ionize and meanwhile fragmented. The detector detects the charge to mass ratio of the ion and produces spectrum according to their abundance. Nominal mass is the mass of molecular ion of most abundant isotope, where mass defect is not considered.

3) The following molecule, chloral is a common precursor to chloral hydrate, an acetal type molecule that was a first-generation anesthetic. Draw a mechanism that accounts for tis formation and speculate why it does not require the use of an acid catalyst, like most hemiacetal and acetal reaction: (10 pts) H H₂O

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
