If the atomic mass unit \( u \) were defined to be \( \frac{1^{\text {th }}}{5} \) of the mass of an atom of \( C-12 \), what would be the atomic weight of nitrogen in amu or \( u \) in this state? Atomic weight of \( \mathrm{N} \) on conventional scale is 14 :
a. \( 6.77 \mathrm{u} \)
b. \( 5.834 \mathrm{u} \)
c. \( 14 \mathrm{u} \)
d. \( 23 \mathrm{u} \)
