What is the mass of carbon in 16.0 g of methane? 2. Show the set-up that would be used to determine the percent by mass of carbonHowever, the mass is not defined this way – one writes for the mass of an infinitesimal volume of material – a mass element, dm =ρ(x,t)dv (3.1.3) or, for the mass of a volume v of material at time t, =∫ ( ) v m ρx,t dv (3.1.4) 3.1.2 Conservation of Mass The law of conservation of mass states that mass can neither be created nor destroyed.If M is the molecular mass of the analyte protein, and n is the number of positive charges on the protein represented in a given m/z peak, then the following equations gives the molecular mass M of the protein for each peak: Mpeak2 = n(m/z)peak2 − n(1.008) (1) (1) M p e a k 2 = n ( m / z) p e a k 2 − n ( 1.008)The mass in grams of one mole of substance is called its molar mass. For an element or compound that is composed of molecules, the molar mass in grams is numerically equal to its molecular weight in atomic mass units. The molar mass of a molecular substance contains an Avogadro's number of molecules of the substance. For CO2 (m.w. = 44.01 u),

These two factors are combined into the mass/charge ratio. Mass/charge ratio is given the symbol m/z (or sometimes m/e). For example, if an ion had a mass of 28 and a charge of 1+, its mass/charge ratio would be 28. An ion with a mass of 56 and a charge of 2+ would also have a mass/charge ratio of 28.
