Question: what is 0.2 n hcl?
Answer: 0.2 is one sixtieth of 12. Thus 1 ml concentrated hydrochloric acid plus 59 ml water is a 0.2 N. If you need a lot of 0.2 N hydrochloric acid, you can add 16.5 ml of concentrated hydrochloric acid to 983.5 ml water (or add enough water to 16.5 ml concentrated hydrochloric acid to make 1 liter of total solution).
