Hello!

I need to make following solution:

Components	Concentration
Cysteine	50 mg/L
Histidine	25 mg/L
Methionine	25 mg/L
MnCl2	20 M
CaCl2	0.18 mM
Yeast Extract	5 g/L
Fructose	5 g/L
MgCl2	1 mM

How to prepare 100X stock solution of 5g/L yeast extract? (final volume of the stock solution is 200 mL)

How to prepare 100X stock solution of 5g/L fructose? (final volume of the stock solution is 200 mL)

How to prepare 100X stock solution of cysteine, histidine, methionine (final volume of the stock solution is 50 mL)?

How to convert 20 micromoles of MnCl2 to g/L? How to prepare 100X and 1000X stock solutions of 20 micromoles of MnCl2? (final volume of the stock solution is 50 mL)?

How to convert 0.18 millimoles of CaCl2 to g/L? How to prepare 100X and 1000X stock solutions of 0.18 millimoles of CaCl2? (final volume of the stock solution is 50 mL)?

How to convert 1millimole of MgCl2 to g/L? How to prepare 100X and 1000X stock solution of 1millimole of MgCl2? (final volume of the stock solution is 50 mL)?

If the final volume of the solution is 50 mL how many milliliters of each above solutions is required?

Please give me step by step solution..
