WebbCo(NO3)2 + 6 NH3 → [Co(NH3)6]2+ + 2 NO3-From the equation, we see that one mole of Co(NO3)2 reacts with six moles of NH3 to form one mole of [Co(NH3)6]2+. Therefore, we need to calculate the number of moles of Co(NO3)2 and NH3 in the solution mixture and use that information to determine the number of moles of [Co(NH3)6]2+.
