Make 5× M9 salts:

64 g Sodium phosphate (dibasic, 7 hydrate) Na2HPO4•H2O
15 g Potassium phosphate (monobasic) KH2PO4
2.5 g Sodium chloride, NaCl
5 g Ammonium chloride NH4Cl
Add dH2O to 1 liter. Autoclave.

Combine the following ingredients (all pre-sterilized):

200 ml 5× M9 salts
2 ml 1M Magnesium sulfate MgSO4
0.1 ml 1 M Calcium chloride CaCl2
40 ml 10% (w/v) glucose (or other carbon source)
Add sterile dH2O to 1 liter. Autoclave.

To make M9 plates add the items above to 16g of sterilized agar.
If making less than 1 liter use 8g of agar per 500ml of solution.
