How many moles of HCl is in 200 mL of hydrochloric acid solution that has a pH of 1?
PH of 1 means the [H+] concentration is 1.0 x 10-1
Molar concentration is mols HCl in 1000ml solution . so 0.1 = 0.1 mole in 1000 ml.
This is equal to 0.1/1000 = x/ 200
Therefore x = 0.1 x 200 /1000
x= 0.1/5 = .02 mol HCl
Answer: 0.02 mole HCl
