Methionine, an amino acid used by organisms to make proteins, can be represented by the following ball-and-stick molecular model. Write the formula for methionine, and give its molecular weight (red = O, black = C, blue = N, yellow = S, white = H).
Interpretation:
The formula and molecular weight for methionine and should be determined by using the given ball- and- stick molecular model.
Concept Introduction:
Molecular Formula: It is the simplest representation of composition of chemical substance where each and every type of atom is written with the total number of the atom present in the substance.
Molecular weight: The sum of mass of all atoms present in formula of chemical substance is referred as molecular or formula weight of that substance.
