You are given a flask containing 0.50 M CUSO4 and you need 100 mL of 0.15M CUSO4. How much of the 0.50 M solution must you use to
prepare the required solution?
So, one mole of NaCl weighs 58.44 g. A 2.5 M solution is 2.5 moles per liter (Molarity is just the number of moles per liter). Therefore, 0.5 L would contain 1.25 mo
