What is the molecular mass of 1 mole of a compound whose formula is c3h7o2?
The same as the molecular weight of the compound.
What is the molecular compound for N2F4?
The chemical name of Tetrafluorohydrazine has the molecular formula N2F4. Tetrafluorohydrazine is a toxic organic compound with a molecular weight of 104.0 grams per mole.
How do calculate how many mole are in grams?
For these conversions, you need the atomic masses of the elements involved in grams. If it is just one element, then you use the atomic mass, but if its a compound, then use the molecular mass (added atomic masses). Take the number of moles and multiply it by the atomic (molecular) mass to get number of grams.

How to calculate grams per liter?
You haven't stated the compound so we cannot calculate the molecular weight. However, first off here, you have to multiply by 1000 to convert grams to milligrams. Next you divide by the molecular weight. The volume does not need adjusting.
