Basically it is the difference between a quantity and a concentration. 0.5 mole HCl means approximately 17.73 gram of HCl. 0.50M HCl means that quantity of HCl per litre of solution.
So if you had two litre of 0.50M HCl solution, you would have 35.46 gram of HCl, but 0.5 mole HCl always means just 17.73 gram.
There are two other issues -- the first is an issue of precision. 0.5 mole in scientific practice means anything between 0.45 and 0.55 mole, that is (in this case) a ±10% margin of error. So 0.5 mole HCl might be anywhere between 16.0 and 19.5 gram. But 0.50M HCl is much more tightly constrained -- between 0.495 and 0.505 mole per litre, meaning between 17.55 and 17.91 gram per litre. The second is, of course, that with any chemical element whose symbol is 2 letters, like Cl, the second letter must be lower case -- Cl, not CL.

What is the mole fraction of HCl in an aqueous solution that is 27.2 percent HCl by weight?
The mole fraction of HCl is 0.34.
What is the stoichiometric relationship between NaOH and HCl?
These chemicals react in a direct proportion of one to one, measured in moles of course, not by weight. A mole of NaOH weighs more than a mole of HCl.
Is there a difference between Venlafaxine and Venlafaxine HCL?
no
What is the concetration of 400 ml of 0.5 M HCl?
Since the molecular weight of HCl is 36.46g/mole, 1 mole of HCl contains 36.46g. 1 liter of a 0.5M solution will have 18.23g of HCl. 400 ml will have 7.292g of HCl.
What is the limiting reactant of 0.5 mol of zinc to 0.75 mol of hydrochloric acid?
Balanced equation first.Zn + 2HCl --> ZnCl2 + H20.5 mole Zn (2 moles HCl/1 mole Zn)= 1 mole HCl================you do not have this much moles HCl0.75 moles HCl (1 mole Zn/2 mole HCl)= 0.375 moles Zn===================you have more moles Zn than thisSo. HCl limits this reaction.
