What is the number of atoms per element with Cr (NH3) 6 (NO3) 3

The number of atoms per element with Cr (NH3) 6 (NO3) 3 is as below

Chronium (Cr) = 1

Nitrogen (N) = 9

Hydrogen (H) = 18

Oxygen (O) = 9

Explanation

Cr (NH3) 6 (NO3) 3 has four element, that is chronium (Cr), Nitrogen (N), Hydrogen (H) number of atoms per element in Cr (NH3) 6 (NO3) 3 is determined as follows for Cr is = 1 to since there is only one atom of Cr

N = (1 x 6) + (1 x3) = 9 atoms

H = 3 x6 = 18 atoms

O = 3 x3 = 9 atoms
