A student preapred a stock solution of the assigned compound by weighing 2.345 grams of Cu(No3)2 6H20 [nickel(ii) nitrate hexahydrate] and diluting it with water to a final volume of 25.00 mL.
From this stock solution, the student then took 2.00mL and diluted it to a final volume of 10.00mL with water. What is the final concentration of this diluted solution?
