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.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
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.
There are 1,000 milligrams per gram. 0.2 grams*(1000 milligrams/gram) = 200 milligrams
The numbers are equivalent. For example, 5 grams per 100 grams = 5%.
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
divide by the molecular mass, (units of gram per mol)
1000kg or 1,000,000 grams
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!
1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).

It depends on the type of gasoline, and other factors such as temperature and pressure, but gasoline has an approximate density of 737.22 kilogram/cubic meter. 737.22 kilogram/cubic meter = 0.73722 kilogram/liter = 737.22 gram/liter 42.4 liters * 0.73722 kilograms/liter = 31.258 kilograms or since you wanted grams, not kilograms... 42.4 liters * 737.22 gram/liter = 31258 grams(http://forum.onlineconversion.com/showthread.php?t=1114)
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)
Kg stands for kilogram, which means 1000 grams. So 1 gram = 1/1000 of a gram.
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.
