25.0 mL of a 6.0 M HNO_3 stock solution is dated using water to 100 mL. How many moles of HNO_3 are present in the dilute solution? 1.5 moles 0.6 moles 0.15 moles 6.0 moles How many mL of a 14.0 M NH_3 stock solution are needed to prepare 200 mL of a 4.20 M dilute NH_3 solution? 60.0 mL 667 mL 840 mL 0.060 mL The four following concentrated solutions are each diluted with water to form 200 mL of a dilute solution. Which solution, once diluted to 200mL, will have the largest concentration? 20.0 mL of a 0.4 M NaOH solution 80.0 mL of a 0.2 M NaOH solution. 10.0 mL of a 0.5 M NaOH solution 100.0 mL of a 0.1 M NaOH solution
