Hi, I am really stuck on example 4.13 and cannot reconcile the approach to answering it with example 4.12. I was hoping someone could walk me through 4.13. I don't understand why you are multiplying CaCO3 by 2. I would think you would multiply HCl by 2. Can someone please explain it to me in simple terms. Explain it to me like I'm a 6th grader bc I am lost. I also don't get how the approach you take for 4.13 is different from 4.12. Thanks so much! I have reproduced each question below:
4.12 How many ml of .4 M NaOH are required to neutralize 100 ml .25 M H2SO4?
answer: 125
4.13 How many ml of .6 HCl are required to neutralize 3 grams of Caco3?
Answer 100 ml
