The molar mass of CO2 is
Mr (C)=12.01
Mr (0)=16.00
Therefore, the molar mass is (12.01+(16.00x2) since there are 2 oxygen atoms then the molar mass will be doubled for oxygen therefore,
Molar Mass=48.01 g/mol

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 are the gram molecular weights ofC6H8O7?
gram molecular weight of C6H8O7=(atomic weigth of carbon X 6)+(atomic weigth of hydrogen X 8+(atomic weigth of oxygen X 7) grams
How many moles of CO2 molecules are present in 11g of carbon dioxide?
molecular weight of carbon dioxide = 44u gram molecular weight of carbon dioxide = 44g given mass = 11g no. of moles = given mass divided by molar mass = 11 divided by 44 = 0.25moles.
Specific gravity of oxygen is?
Start with the molecular weight of oxygen, twice the atomic weight because it's O2. So the molecular weight is 32. Now at school you learn that a gram-mole of any gas occupies 22.4 litres. A gram-mole of oxygen weighs 32 grams (1 gram times the molecular weight). Therefore 32 grams of oxygen occupies 22.4 litres (at normal temperature and pressure). 22.4 litres of water (specific gravity = 1) weighs 22400 grams. Therefore the specific gravity is 32/22400 = 0.00142857 . . That's it!
What is the weight of iodine?
gram-Equivalent of iodine is 127 because its molecular weight is 2(127) and 2 electron change involve in the redox titration
Is gram equivalent weight equal to molecular weight divided by two?
25.5molecule
What is the difference between treaty v executive agreement?
molarity x molecular weight x volume=gram molarity= gram/molecular weight x volume abdulrazzaq
What is the gram molecular weight of 3.92 grams of oxygen?
62.72
Difference between Gram atom and gram molecule?
It's much simpler than you're probably thinking. You use the term gram atomic weight for atoms, and the term gram molecular weight for molecules. That's all. The gram molecular weight of a molecule is the sum of the gram atomic weights of the atoms making up that molecule.
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.
How do you get gram molecular weight?
gram molecular weight = weight of one mole of the substance in grams for example 1 mole of water weighs 1 + 1 + 16 = 18 grams so gram molecularweight of water is 18g

What is a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.
What weight of nitric acid can be produced from 18.5 gram of nitrogen dioxide?
10.0gm
How can you use moles to solve problems?
moles can be used to calculate gmv(gram molecular weight)
What are the gram molecular weights ofC6H8O7?
gram molecular weight of C6H8O7=(atomic weigth of carbon X 6)+(atomic weigth of hydrogen X 8+(atomic weigth of oxygen X 7) grams
