Yellow CdS pigment is prepared by reacting ammonium sulfide with cadmium nitrate. What mass of CdS can be prepared by mixing 2.50 L of a 1.25 M Cd(NO3)2 solution with an excess of (NH4)2S?

Question

Cd(NO3)2 + (NH4)2S ---> CdS + 2NH4NO3

Could someone give me a step by step description of how to solve this?

Answer 1

Moles Cd(NO3)2 = M x L = ??
Using the coefficients in the balanced equation, convert moles Cd(NO3)2 to moles CdS.
Convert moles CdS to grams. g = moles x molar mass.
