.5 means it is half in percentage. in a liter ofcourse.
if 1M it would be 1N in HCL concentrations.

Answer 2

Can you be more spesific about that 1N thing?

Answer 3

The 'N' stands for 'Normal'. In acid/base chemistry, 'Normality' is used to express the concentration of protons or hydroxide ions in the solution. Here, the normality differs from the molarity by an integer value - each solute can produce n equivalents of reactive species when dissolved.

Answer 4

Is there any equation to measure it?

Answer 5

multiply the molarity to the value of N
