Question

how many nitrogen atoms are present in 1 g of K2Zn3[ Fe(CN)6]2.

Answer 1

can u tell me the molecular weight of the complex :)

Answer 2

\[n=\frac{ N }{ Ac } = \frac{ m }{ M }\]
n=no. of moles
m=mass
M=Molar mass (molecular weight)
A(c)=Avogadro's constant (6.02 x 10^23)
N=no. of particles (atoms, ions, etc...)
