Planck's constant

ConvertV= 1000 cm-1 to kJ · mol-1 using the following values for standard constants:

h = 6.626? 10-34 J · s, c = 2.998? 108 m · s-1, NA = 6.022? 1023 mol-1

 

R.) If Planck's constant is taken as h=6.626×10-34 J·s,

then E=h? (per molecule) and E=NAh? (per mole, where NA is Avogadro's number)

and ?=c?,so

E=NAhc?=(6.022×1023 mol-1)(6.626×10-34 J·s)(2.998×1010 cm·s-1)(103 cm-1)

 

= 1.2×104 J·mol-1=12.0 kJ·mol-1
