Which property of a signal contains the number of hydrogen atoms in the set of equivalent hydrogen atoms that caused the signal in a ¹H NMR spectrum?

(•) For the following molecules, give the integration you would expect for the signal associated with the hydrogens at the labeled carbons. [Pay attention to the symmetry, or lack of symmetry, in the molecules.] (e)
