In chemistry, mass ratio, often called "percent composition by mass," is the proportion of a particular molecule that consists of each that molecule's constituent elements. For example, water consists of 11.1 percent hydrogen (H) and 88.9 percent oxygen (O), meaning that a 1,000-gram sample...
As an example, consider sodium chloride, NaCl, the chemical name for common table salt. Sodium chloride is an ionic compound composed of sodium cations, Na+, and chloride anions, Cl–, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu (see Figure 3)....
Relative Formula Mass Definition A related term you should know is relative formula mass (relative formula weight). This simply means the calculation is performed using relative atomic weight values for the elements, which are based on the natural isotopic ratio of elements found in Earth's atmosph...
Rather, it measures the mass-to-charge ratio (m/z) in thomson (Th) of ions from which the relative mass (m) can be derived if the charge number of the ion (z) is known. The relative mass (m) is a dimensionless number which is defined as the mass of an atom, a molecule or ...
The resulting mass spectrum is a plot of the (relative) abundance of the produced ions as a function of the m/z ratio.”(质谱的基础是产生离子,这些离子随后按质荷比大小被分离过滤并被检测。得到的质谱图是产生离子质荷比的相对丰度图谱。)Niessen, W. M. A.; Van der Greef, J., Liquid ...
