Cu +2NH3 = Cu(NH3)2 Kt= 6.3 × 10^10
Calculate K
Cu + 2NH3 = Cu(NH3)2
kf = 6.3 ×10^10
The ksp for CuBr = Cu + Br = 6.3 × 10^-9
For the reaction; CuBr +2NH3 = Cu(NH3)2 + Br to calculate K?
K = (6.3 × 10^10)(6.3×10^-9)
Thus K is 396.9

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Electron has -1 charge while proton has +1 charge. Neutron is neutral.

(mass of strontium) / (mass of compound) * 100% = (percent mass of Strontium)
1. The mass of strontium is 87.62 and the mass of Chlorine is 35.45. There are 2 chlorine atoms in the compound, so 35.45*2 = 70.9. Add the strontium to get the mass of compound. 70.9 + 87.62 = 158.52. Now, we can use the equation.
87.62 / 158.52 * 100% = 55.27% Strontium
2. There are 2 Iodine atoms in the compound, and the molar mass of Iodine is 126.9. The mass of the compound is 126.9 + 87.62 = 214.52. Now, we can use the equation
87.62 / 214.52 * 100% = 40.84% Strontium
3. The molar mass of Oxygen is 16, and there is only one oxygen atom. So the mass of the compound will be 16 + 87.62 = 103.62. Now we can use the equation.
87.62 / 103.62 * 100% = 85.46% Strontium
4. Finally, the molar mass of sulfur is 32.06, and there is only one sulfur atom in the compound, so the mass will be 32.06 + 87.62 = 119.68. Now we can use the equation
87.62 / 119.68 * 100% = 73.21% Strontium
Therefore, the answer is 3 because it has the highest percentage of Strontium than the other compounds. Hope this helped!! :D
