To find the number of moles of HBr, we need to divide the given number of molecules by Avogadro's number (6.022 x 10^23 molecules per mole).

Number of moles of HBr = 1.21 x 10^23 molecules / (6.022 x 10^23 molecules/mole)
                          = 0.201 moles

Therefore, the correct option is (C) 2.01.
