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.
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.
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.

To make 50 ml of a solution with a concentration of 500 mg per 5 ml, you would need to calculate the total amount needed: 50 ml / 5 ml = 10 units of 5 ml that are needed. Since each unit of 5 ml requires 500 mg, you would need 10 units x 500 mg = 5000 mg. To find out how many 250 mg tablets are needed to make 5000 mg, you would divide 5000 mg by 250 mg per tablet, which equals 20 tablets needed.
It is 500 mg amoxicillin.
500 mg = 0.5 g500 mg = 0.5 g500 mg = 0.5 g500 mg = 0.5 g500 mg = 0.5 g500 mg = 0.5 g
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.
To calculate the concentration of the sucrose solution, you would divide the amount of sucrose (125 mg) by the total volume of the solution (500 ml) and then convert the units as needed: Concentration of sucrose solution = 125 mg / 500 ml = 0.25 mg/ml = 0.25 g/L
Two
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.
20 tablets are necessary.
