A student prepared a stock solution of the assigned compound by weighing 2.345 grams of Cu(NO3)2. 6H20 and diluting it with water to a final volume of 25.00mL.
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?
