Not sure what a cubic gram is.
Grams per litre is simple a measure of density. Whatever cubic grams is, it is not a measure of density and so these two measure different things. Therefore, according to the rules of elementary dimensional analysis, conversion from one to the other is not valid.
Gases normally have a density of a few grams per liter (i.e., per cubic decimeter), at most. Air, for example, has a density of about 1.2 grams per liter, at standard temperature and pressure. The standard SI unit for density would be kilogram per cubic meter (which actually happens to be equivalent to grams per liter!), but many people are still accustomed to specify the density per liter, not per cubic meter.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
The numbers are equivalent. For example, 5 grams per 100 grams = 5%.
There are 1,000 milligrams per gram. 0.2 grams*(1000 milligrams/gram) = 200 milligrams
One gram equals 1,000 milligrams.
The question is meaningless. No such thing as a cubic gram.
1 cubic cm = 1cc = 1 miliiliter = .001 liter 1 gram = 1000 mg 1 gram/cc = 1000 mg/.001 liter = 1,000,000 mg/liter
1 liter of water has a mass of 1000 grams since there are 1000 cubic centimeters in a liter.
Grams and cubic centimeters are interchangeable. 100g of water = 100cm3 of water.
1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.
You need to know the volume of liquid that contains the solid to answer this question. If you have one liter of a solution that contains 0.1 grams per milliliter, you can find the number of grams in the container through this calculation: 1 liter X 1000 ml/liter X 0.1 grams/ml = 100 grams of solid in the one liter of solution (the units for liters cancel out)

That is impossible. Length can never be converted to weight or mass. Actually it is possible. You must first convert the meters to cubic decimeters. 1 cubic decimeter is equal to 1 liter. So then you convert the liters to mililiters. 1 mililiter is equal to 1 gram. It is funny to convert linear length meter to a volume. Magic!
One liter of water weighs one kilogram. One kilogram is 1,000 grams. One liter is 1,000 cubic centimeters (a.k.a. "cc" or "ml") So: One cc weighs one gram. Isn't the metric system wonderful?
This question cannot be answered sensibly. A litre 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 litre of air and a litre of water. They will have very different masses.
The numbers are equivalent. For example, 5 grams per 100 grams = 5%.
