Polymers in Condensed Formulas
For polymers in condensed chemical formulas, parentheses are placed around the repeating unit. For example, a hydrocarbon molecule that is described as CH3(CH2)50CH3, is a molecule with fifty repeating units. If the number of repeating units is unknown or variable, the letter n may be used to indicate this formula: CH3(CH2)nCH3.

Famous quotes containing the words condensed and/or formulas:
“There is no doubt that the loftiest written wisdom is either rhymed or in some way musically measured,—is, in form as well as substance, poetry; and a volume which should contain the condensed wisdom of mankind need not have one rhythmless line.”
—Henry David Thoreau (1817–1862)
“It is sentimentalism to assume that the teaching of life can always be fitted to the child’s interests, just as it is empty formalism to force the child to parrot the formulas of adult society. Interests can be created and stimulated.”
—Jerome S. Bruner (20th century)
