Moles of copper ll chloride in 2 ml and 0.03M solution= molarity × volume in litre
= .03 mole/L × 2 × 10^-3 L
=6 ×10^-5 mole CuCl2
Because Copper ll Chloride and H2salen are in 1:1 ratio so moles of H2salen = 6×10^-5 mole.
As mole = mass / Molar mass
So mass of given compound H2salen =
= Moles × Molar mass
= 6 × 10^-5 mole × 268.3 gMole^-1
=16098 × 10^-5
=0.16097 g answer

Lab procedure: This laboratory exercise involves the use of dilute sulfuric acid (H2SO4) to leach copper from a synthetic copper-containing ore, malachite. This technique is known in the mining industry as solution mining. The soluble copper is then filtered to remove unreacted ore (the residue) from the filtrate containing the copper+2 ion. The copper in the filtrate is then treated with metallic magnesium to precipitate the copper as the familiar orange-brown metal. This copper is dried and weighed. From these...
