The paper I'm currently reading mentions [HAuCl4]=50 mgmL^-1
What does this even mean? Here's another larger excerpt
"The initial concentrations of HAuCl4 and a-d-glucose
were 50 mgmL1 and 0.2 m, respectively, and the ultrasound
irradiation time was 1 h. The geometrical configuration of the
nanobelts is clearly displayed in the SEM images"
Again
[HAuCl4]=50 mgmL1
, [a-d-glucose]=0.2
m, ultrasound time=1 h

It means the concentration of chloroauric acid is 50 mg/ml.
The 2M means a concentration of 2 molar, as in 2 moles of glucose per litre.

If you don't know what the concentrations mean... I doubt you can use HAuCl4.
