A millilitre is a unit of capacity. A gram is a unit of mass. Without some other factor such as density, it would be impossible to calculate the mass of a capacity.
The material type and/or density is missing
10g = 10ml of water, other liquids may vary
420 mL of water is equal to 420g. 1 mL of water is 1g.
18 grams if sugar
That is 90 grams.
Depends on the substance...if it is water, it will be 750 grams
280 ml of water is 280 grams
none
There is not enough information to determine, because grams is a measure of WEIGHT and mls is a measure of LIQUID. <<<adr>>>
The material type and/or density is missing
No, mls (or milliliters) is a measure of volume while grams is a measure or weight or mass.
That is approximately 230 grams
10g = 10ml of water, other liquids may vary
You divide the grams by the density.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
18 pounds is 8164.66 grams.
18 kg = 18000 grams
