It means, weigh about 5 grams of NaCl, precisely, to the milligram. I don't really know how to make it much simpler than that.
Maybe this will help. 5 grams is 5000 milligrams. The value you get for the sodium chloride you weigh out will probably be between 4900 and 51000 milligrams. Anywhere in that range is fine.
The instruction means: "Take a quantity of approximately 5 grams of NaCl, and by weighing,
determine its actual weight, with sufficient precision that the figure you state is wrong by
not more than 1 milligram."

5 grams of NaCl, or table salt, is equal to 5,000 milligrams. to convert grams to milligrams you simply multiply by 1,000.
When the water froze into ice it was expanding (thermal expanision) causing the 100 grams of ice to have a greater volume than 100 grams of water!
Roughly 16 grams, if you mean 10^23. 6.022*10^23 is Avogadro's Number, which represents the number of atoms or molecules in a mole of any substance. Since the molar weight of oxygen is approximately 16 grams, that's your answer.
