take 0,533 ml of stock solution and add to 49,467 ml  of necessary buffer

Stock concentration = 93.7mg/mL

i.e. 93.7mg in 1000 microlitre

i.e. 9.37mg in 100 microlitre

i.e. 0.937mg in 10 microlitre

i.e. 1 mg in 10.6 microlitre

Hence you can take 10.6 microlitre from stock and add into 49 mL and 989.4 microlitre of buffer/water.

v1c1=v2c2

v1=v2c2/c1=(50 ml*1 mg/ml)/ 93.7 mg/ml = 0.5336 ml

Required vol= 50 ml

So, 0.5336 ml of stock dilute with 49.4664 ml of solvent or buffer

thank you so much sir !
