How many moles of H⁺ in 25.0mL of 0.1M HCl?

The book is saying n=2.5x10³ moles of HCl and also of H⁺

But I keep getting n=2.5x10^-3

My working:
C=0.1
V=0.025
n=CV n=0.1*0.025=2.5x10^-3

The book is incorrect. Theres no way u can have 2500 moles of anything in 25 mL

Yeah, it's probably a miss-print. The book probably meant to have a negative index of 3, which is your answer.
