The molar mass of a substance is the mass of one mole of that substance. What is the unit of molar mass? A. g/mol B. mol/g C. L/mol D. mol/L 相关知识点: 试题来源: 解析 A。本题考查摩尔质量的单位。摩尔质量是指单位物质的量的物质所具有的质量,单位是克每摩尔(g/mol)。选项 B...
The glucose molecule has 6 carbons, 12 hydrogens and 6 oxygens, so its molecular mass is (6 • 12) + (12 • 1) + (6 • 16) = 180. Therefore, one mole of glucose has a mass of 180 grams. If you want to find the mass of more than one mole, multiply the amount in ...
Mass of one mole of protons 1.672xx10^(-24)xx6.023xx10^(23)gm =1.008 gm Mass of one mole of electrons =9.1xx10^(-28)xx6.023xx10^(23)gm =0.55xx10^(-3)gm=0.55mg
Molar mass is the mass of one mole of a substance. M = m n It is normally expressed in units of g mol-1, in which case its numerical value is identical with the relative molecular mass.Citing this page: Generalic, Eni. "Molar mass." Croatian-English Chemistry Dictionary & Glossary...
mass of one mole of the compound expressed in grams. For water: H 2 O Molecular mass = (2 x atomic mass of H ) + atomic mass of O = 2 ( 1.008 amu) + 16.00 amu = Mass of one molecules of water = Molar mass = ( 2 x atomic mass of H ) + atomic mass of O = 2 ( ...
Atomic mass gives us the mass of one atom. Molecular mass gives us the mass of one molecule (mC) •one water (H 2 O) molecule = 18 amu (2-H, 1-O = 2amu + 16amu) •one glucose (C 6 H 12 O 6 ) molecule = 144 amu (6C, 12H, 6O = [6 C x12amu] + [12 H x 1...
Calculate the mass and charge of one mole of electrons. Given: Mass of one electron = 9.10×10−31 kg Charge of one electron = 1.602×10−19 coulomb Solution Verified by Toppr Mass of 1 mole of electrons: 9.10×10−31×6.023×1023=5.486×10−7 kg Charge of 1 mole of electro...
(2001), investigated the effect of simple and complex carbon sources on the molecular weight of PHB produced byAzotobacterchroococcum.The molecular mass of PHB produced did not change by increasing the concentration of glucose as a carbon source (in the range of 400–500 kDa), while by ...
One mole of a substance has a mass （equals）_to its relative formula mass in grams, contains （identical) atoms, molecules or formula units.
(atoms, molecules, ions, etc.) as the number of atoms in a sample of pure12C weighing exactly 12 g.One Latin connotation for the word “mole” is “large mass” or “bulk,” which is consistent with its use as the name for this unit. The mole provides a link between an easily ...
