mg/ml = M (Molar) ?
Is that right? or does mg/ml = something else?
Thanks
Of course you are correct. Take the following example:
In order to prepare a 1M solution of (as an example) NaOH, you would take 40g NaOH and dissolve to a volume of 1 litre.
Now divide 40g by 1000 and you have 40mg
Now divide 1 litre by 1000 and you have 1ml
Therefore 40mg/ml = 40g/litre = 1M NaOH
1 mole per litre has a molarity of 1.
1 mg per ml is just that, 1 mg/ml.
Divide the mg/ml by the molecular weight to get the Molarity
Concentration (mg/ml) / Molecular weight (gram/mole) = Molarity (mol/L)

RE:
Does mg/ml equal = 1 Molar?
1 MOLAR = 1 mol/dm^3
1mg / 1000 = 10^-3 g
1 mol = 10^-3 g / Molar mass
1ml = 1 cm^3 =10^-2 dm^3
from the dimensions,
1 MOLAR = 1 mol/dm^3 is not equal to
(10^-3 g / Molar mass)/(10^-2 dm^3)
mg/ml is not equal to molarity.
mg/ml=STRENGTH OF SOLUTION.(M/V)
ITS UNIT IS ALSO g/ml
