The answer depends on the temperature. It will range from 1 ml (at 4 deg C) to 1.043 ml at 100 deg C.
For water (this only applies to water): grams = milliliters.
400g of what?
Only if you have pure water in mind: 10 milliliters of pure water weigh 10 grams.
Milliliters can't be converted to grams. Milliliters measure volume, while grams measure mass.
290 grams of water is 290 ml.
26 grams of water is 26 ml.
120 ml of water weighs 120 grams
16 ml of water is 16 grams
Thirteen grams of water is the same as thirteen milliliters. So, if thirteen grams of water were added to the beaker, then thirteen milliliters of water were added.
5.5 grams of water is 5.5 ml.
205 grams of water is 205 ml
The conversion of grams to milliliters depends on the density of the substance. For water, 1 gram is approximately equal to 1 milliliter. So, 1.8 grams would be roughly 1.8 milliliters.
