Equivalent ways of saying this are: There are likely to be 111 1³C atoms in a sample of 10,111 carbon atoms or 1.10% of the carbon on the planet is 1³C (since 111/10,111 x 100% = 1.10%).

What is not true about mass spectrometry? Question 13 options: Only the molecular ion and cationic fragments are deflected, and they are then separated by their mass-to-charge ratio (m/z) It is used to determine the molecular weight and molecular formula of a compound. In a mass spectrometer, a compound is converted into ions, which are then separated by a magnetic field. In a mass spectrometer, a compound is first vaporized and then bombarded with electromagnetic radiation which generates a radical cation that is symbolized by (M)+• A molecular ion is often very unstable and susceptible to fragmentation
