The question, as stated, cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
As a simple mental exercise consider a millilitre of air and of water. They will have very different masses.
A typical plastic drinking straw weighs around 0.4 grams.
An empty 500 ml plastic bottle typically weighs around 10-15 grams.
300 ml of water weighs approximately 300 grams.
As water has a specific gravity of 1, 10ml = 10cc. Now, a centimetre is a unit of length, equal to 1/100 of a metre; thus, 1 cc = 1/1,000,000 of 1 metre. Therefore, 10 cc = 10/1,000,000 cubic metres = 1/100,000 of a cubic metre.
10 cm3 of water would displace an equivalent volume of water when submerged. This displacement would be equal to 10 ml or 10 grams of water.
10 GRAMS
10 ml of water weighs 10 grams
A cc, or cubic centimeter, of water is equal to 10 g, or grams, and 10 ml, or milliliters.
The density of bromine is 3.12 g/ml, therefore 10 ml of bromine would weigh 31.2 grams.
Density = mass/milliliters Density = 10 grams/2 ml = 5 g/ml ---------------
How much does 100 ml of vinegar weigh in grams?
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
That is 10 grams of liquid creamer.
If it is water, 10 grams
The mass of the substance is 20 grams in a 10 ml sample. Therefore, the substance has a density of 2 grams/ml. For a 200 ml sample of the same substance, the mass would be 400 grams (200 ml x 2 grams/ml).
A typical plastic drinking straw weighs around 0.4 grams.
Density is calculated by dividing the mass of a substance by its volume. In this case, if the mass of the liquid is 10 grams and it occupies a volume of 1 mL, the density would be 10 grams per 1 mL, or simply 10 g/mL.
