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
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.
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
Equivalent weight of sodium thiosulphate is equal to its molecular weight why?
The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; e.g., potassium permanganate (KMnO4) in acid solution, 158.038/5 g; potassium dichromate (K2Cr2O7), 294.192/6 g; and sodium thiosulfate (Na2S2O3·5H2O), 248.1828/1 g. In case of Sodium Thiosulfate the reation proceeds as under: I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI 2 Na2S2O3 ≡ I2 ≡ Cl2 ≡ 2 e Hence Na2S2O3 ≡ 1 e Thus Molecular weight devded by 1 is the equivalent weight & hence both have same value
What is the process to calculate the gram molecular weight of the unknown liquid?
To calculate the gram molecular weight of an unknown liquid, you need to determine the molecular formula of the liquid and then add up the atomic weights of all the atoms in the formula. This will give you the gram molecular weight of the unknown liquid.
Is gram equivalent weight equal to molecular weight divided by two?
No, gram equivalent weight is molecular weight divided by n, where n is the number of equivalents of the substance involved in the reaction. It is not always equal to molecular weight divided by 2.
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
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 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
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.
How much gram in a millimole?
The number of grams in a millimole depends on the molecular weight of the substance being measured. To calculate it, you need to know the specific molecular weight of the substance.
What is the gram molecular mass of hydrogen?
The gram molecular mass of hydrogen is 1 gram per mole.
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.
How can you use moles to solve problems?
moles can be used to calculate gmv(gram molecular weight)
