HCl as it is purchased is approximately 12 molar (read the analysis on the label for exact molarity of a given lot). Therefore, diluting concentrated HCl with an equal volume of water results in a (approximately) 6 molar (6M) solution.

The M stands for molarity. Molarity is the number of moles of solute (HCl) per liter of solution. The higher the molarity the stronger the concentration of the acid.

M refers to molarity. It means 6 moles of HCl per Liter of solution. You would say it was a "6 molar solution of HCl."

Big M stands for "Molarity".
It is a unit for the concentration of a solute in a solution.
To get molarity...
Moles of solute / Volume of solution in liters
Sometimes it's more convenient to express molarity in mol/L as opposed to a big M to avoid getting confused. :)

Molar. It means Moles per Litre.

molar. its a measurement of concentration. Moles/Litre to be exact.

Here's a pretty good tutorial on molarity.

It's referring to moles.
