In the reaction of colorless solutions of cobalt(III)

In the reaction of colorless solutions of cobalt(III) chloride and ethylenediamine
(C2H8N2) a dark orange solution is formed.
The reaction proceeds:
CoCl3 + 3NH2CH2CH2NH2 → 2HCl + Co(NH2CH2CH2NH2)3Cl3
If the reaction takes place by mixing 10 mL of 0.01 M solution of CoCl3 and 10
mL of 0.06 M solution of C2H8N2, determine:
a) The number of moles of CoCl3
b) The number of moles of C2H8N2
c) The limiting reactant
d) The theoretical yield of Co(NH2CH2CH2NH2)3Cl3
