The answer depends on the density/volume of the substance being measured.
If the substance is water, or the same density as water:
1 ml of water = 1 gram, therefore -
0.5ml of water = 0.5 grams = 500 mg
the best way to measure 500mg of something would be to use small scales, accurate to at least 0.1 of a gram.
Gas syringes typically come in a range of sizes from 1 mL to 100 mL, with 10 mL and 50 mL being common capacities. The size needed depends on the volume of gas to be collected or dispensed.
That depends what substance is in the 500 ml volume, and how much mass is in each ml of that substance. If the 500 ml are full of stones or lead, they contain many many mg of mass. If the 500 ml are full of water, they contain roughly 5,000 mg of mass. If the 500 ml are full of air, they contain far fewer mg of mass. If the 500 ml are empty, they contain no mg of mass at all.
0.005 ug/ml
Twenty 250 mg tablets are needed to make 50 mL if the concentration is to be 500 mg per 5 mL.
It is 500 mg amoxicillin.

This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams and milligrams (mg) are measures of weight or mass.
Two
A liquid medication should not be measured in mg. It is a liquid and the base unit for a liquid is liter. It might be milligram per milliliter (mg/mL), but not milligram.
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
Medical syringes measure in cc and ml.
The prefix "milli-" means one one thousandth. 50 milligrams is the same as 0.05 grams.
