Often in the lab, you are given a stock solution that you must dilute before you can use in the lab. For instance, HNO comes as 18.3 M. There are serious biological/safety hazards with using 18.3 M HNO, (it can give you chemical burns within seconds of contact), but it can make a lot of solutions for laboratory use. Usually, we use 1 M HNO, in chemistry class. You will figure out how to do this dilution calculation and many others using a formula that chemists use daily: 1) You add 1.00 Liter of H2O to a 2.00 Liter, 5.00M solution of HCI. What is the concentration of this new solution? 2) How much 18.3 M HNO, is needed to make 1.0 L of 1.0 M HNO₂?
