Concept explainers
Interpretation:
Chemical symbols for the elements oxygen, hydrogen, carbon, and nitrogen has to be chosen from the given options.
Concept Introduction:
Every element has a unique name and in most cases it was selected by the person who discovered it. For an element, abbreviation known as chemical symbol also exist for all elements name. Chemical symbol is simply one- or two-letter designation given for an element that is derived from the name of element. Chemical symbols occupy less space compared to chemical names.
In a chemical symbol, the first letter is always capitalized while the second letter is present in lower case. Two-letter chemical symbols are often the first two-letters of the chemical name of an element. Some elements symbol are derived from the Latin name of the element.

The following volumes of a standard solution of phenobarbital containing 2.000 µg/mL of phenobarbital were then introduced into each flask and the mixture was diluted to volume: 0.000, 0.500, 1.00, 1.50, and 2.00 mL. The fluorescence of each of these solutions was measured with a fluorometer, which gave values of 3.26, 4.80, 6.41, 8.02, and 9.56, respectively.
