- Transfer 0,057 mL of 30 % ammonia solution, with the aid of a micropipette in a volumetric flask (volume 100 mL)
- Add distilled (or demineralized) water up to the mark, at 20 0C
- Put the stopper and stir.
Diluted Ammonia solution can be prepared by diluted strong ammonia solution with the appropriate quantity of purified water.
A solution of ammonia can be used to prepare ammoniumsulfate by reacting it with a solution of sulfuric acid to produce a solution of ammonium sulfate, which can be dried if desired to prepare solid ammonium sulfate.
Check what it is dissolved in first and use the same solvent for dilution. If you want to make a litre of 10% for instance, You want to dilute it 10 in 26 parts or 5 in 13. So 1 litre /13*5 is 384.6ml of 26% ammonia, and dilute to 1 litre with solvent
By dilution of 1 part 0.50M buffer with 49 parts of water, giving 50 parts of the desired 0.010M = 10 mM Phosphate buffer
You have to prepare some nitrates in the lab.Can you make nitrates from ammonia?

You have to dilute the 10 mM NaCl 100X, 33,333X and 10X (X means "times") e.g. 100X: mix 10 ml of 10 mM Nacl with 990 ml of water (= 0,1 mM) 33,333X: mix 30 ml of 10 mM NaCl with 970 ml of water (= 0,3 mM) 10X: mix 100 ml of 10 mM NaCl with 900 ml of water (= 1 mM)

10 mm x 6.0 m = 10 mm x 6(1,000 mm) = 10 mm x 6,000 mm = (10 x 6,000) (mm x mm) = 60,000 mm^2
100 1 cm = 10 mm 10(1 cm) = 10(10 mm) 10cm = 100 mm
