Hi! I am looking at a review question about HCl.

"The molar mass of HCl is 36.5g/mol. Therefore, 73 g would be 2.0 moles, but since it is a strong acid, you would get 4.0 moles of particles (in water). "

Can someone please explain the italicized part to me? Two moles of HCl gives off 2 moles of H+ ions. So what is this "4.0 moles of particles?"

Thank you.

Strong acids completely dissociate in water so you would get 2 mol H+ and 2 mol Cl-. Thus 4 mol of oarticles.

Thanks! I feel so silly that I didn't think of this. It is so obvious now. I've been doing questions all day….. UGH! Can I erase this post :oops:
