Molecular weight = 300,000. Concentration = 40,000 ng/ml. Is it possible to find the molar concentration? How do I do it? Thanks.

Molar concentration is a measure of the concentration of a solution. It is defined as moles of solute per litre of solution Molar Concentration is expressed as = moles/litres we need number of moles moles=given weight/molecular weight In your case 40000 nano grams of substance is dissolved in 1ml In 1000ml (or 1 litre) the wt of substance=40000*1000=40000000 ng or 40000000/1000000000gm =0.004gm (1ng=10^-9gm) so 0.04 gm of solute is dissolved in 1litre moles=given weight/molecular weight= 0.04/300000 moles=0.000000133 moles Molarity= 0.000000133mole/litres Hope this will help you,I tried my best to make it simple
