One of the model organisms used in molecular biology is the worm, Caenorhabditis elegans or C. elegans for short. The medium used to grow these worms is quite complex. One of the components of this medium is called S basal. It is composed of 0.1 M NaCl, 0.05 M potassium phosphate and 0.0005% (w/v) cholesterol. You have the following stock solutions and powders available: NaCl powder (molecular weight 58.4), 1 M potassium phosphate, and a 5 mg/ml stock of cholesterol (mol. wt. 386.7). How would you make up 250 ml of S basal?
chemistry/biochemistry help on calculations from stock solutions?
