Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.

What is molecular mass?
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
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 weight of magnesium bicarbonate?
MgCO3 has a molar mass (molecular weight) of 84.3139 g/mol.
What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?
The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
What is the molecular weight of technetium 99?
The atomic mass (not molecular weight) of technetium-99 is 98,906 254 7(21).
How do you calculate number average molecular weight given molecular weight range and fraction?
Molecular weight is just an older term for molar mass. They are the same.
How do you find out molecular wt using density?
I'm not exactly positive. But if you know the volume in grams and the mass (giving you density), then you should be able to figure out the molecular weight. The mass is the same as the molar mass, which I would assume is the same as the molecular weight, but I'm not positive.

What is the difference between molecular weight in amu and molecular weight in grams?
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
What is the molecular weight of 7H2O?
The molecular weight (mass) means the mass of one molecule only so for H2O it is 18 a.m.u for 7H2O it will be total mass 126.
What is the Molecular weight of magnesium bicarbonate?
MgCO3 has a molar mass (molecular weight) of 84.3139 g/mol.
How do you covert 28.4g S to moles S?
no. moles = mass / molecular weight molecular weight = 64.06 mass = 28.4 28.4 / 64.06 = .4433moles sulphur

The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
What is the equivalent weight of anhydrous sodium acetate?
The formula for sodium acetate is CH3COONa and the equivalent weight is the same as the molecular weight (molar mass) which is 82.0343 g/mol.
What is the molecular weight of technetium 99?
The atomic mass (not molecular weight) of technetium-99 is 98,906 254 7(21).
What is the molar mass of cocaine?
Molecular Weight of Cocaine (Free base): 303.35 Molecular Weight of Cocaine hydrochloride: 339.81
