grams measure mass
liters measure volume
your question has no answer, unless you tell us the density of the matter occupying one liter.
a CC of water weighs (approximately) one gram. There are 1000 CCs in one liter, so a liter of water weighs about 1000 grams.

RE:
How many grams are in a Liter?

1000 grams of water fit into a liter

3 grams/liter will not give 3 grams in anything other than a liter. You have to divide/multiply the 3 by whatever multiple of 10 corresponds with the prefix you are trying to find. (i.e. 3g/L = .003g/mL)

Depends on what the material is and what its density is.
For water, there are 1000 grams of water in a liter.

grams are a measure of weight, liters are a measure of volume. To know how much a given volume of fluid weighs, you must know the density of the fluid.
Mass (g) = density (g/l) * volume (l)
Water has a density of 1000g/l, so 1 liter of water weighs 1000 g (1 kg).
Other fluids will have a different density though, and so 1 liter of chloroform (for example) will weigh more than 1 liter of water

No answer.
Gram is for mass, liter is for volume.

1 gram = 1mL
so 1000 grams = 1L

1L = 1000g of water
you must find out what is ocuppying the liter first and convert to grams per liter.

150 ml in gram
