Mass is measured in grams, kilograms, etc. We know that 1 ml of water has a mass of approximately 1 gram,* so we should expect the water to have a mass of approximately 200 grams.
To determine the mass of 200 ml of an actual quantity of water, we would have to weight it. Technically we would have to convert from weight to mass, but in fact, most scales are given with units that express mass, so in effect this conversion has been done already using certain assumptions about the gravitational field being experienced when the weighing takes place. You can weigh your 200 ml of water in a container and then subtract the weight of the container to determine the weight of the water.
*To be exact, 1 milliliter or 1 cubic centimeter of pure water at 4 degrees Celsius has a mass slightly less than 1 gram; in fact, it used to have that value by definition. However, when the kilogram was redefined, that exact relationship was lost. See the link for details.

How would you measure the mass of 100 ml of water?
Find the mass of an empty container using a balance. Fill the container with 100 ml of water and measure the mass again, The difference between the two measurements is the mass of 100 ml of water.
Would a glass of milk be 200 kg in volume?
No. Kilograms are used to measure mass. Liters (and variations of liters, i.e. mL) are used to measure volume.
How many mg in 1 ml of water?
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
How many ml in gram?
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, grams is a measure of weight or mass.
How many ml is in 19.3 g?
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, grams is a measure of weight or mass.
