因为相对) FORMULA MASS就是指1 MOLE的IONIC COMPOUND(GIANT IONIC STRUCTURE)的质量 单位是gmol^-1 MOLAR MASS就是指某ELEMENT的1 MOLE ATOM的质量 单位是gmol^-1 好啦 举点例子啦-V- 1 MOLE的SODIUM ATOM的RELATIVE ATOMIC MASS就是23.0 MOLAR MASS就是23.0gmol^-1... 1 MOLE的OXYGEN GAS...
What is the molar mass?Molar Mass:Molar mass is also known as the atomic mass or molecular weight. The calculation formula of the molar mass can be written as the ratio of compound mass to the number of mole of the compound, and the obtained unit is gram per mole....

Molar Mass of Formic Acid The molar mass of Formic acid, \({\rm{HCOOH}}\) is: \(\left( {{\rm{The}}\,{\rm{atomic}}\,{\rm{mass}}\,{\rm{of}}\,{\rm{carbon}}} \right) + 2\left( {{\rm{The}}\,{\rm{atomic}}\,{\rm{mass}}\,{\rm{of}}\,{\rm{hydrogen}}} \right...
Molar masses of elements The molar mass of atoms of an element is given by the atomic mass of the element [2]multiplied by the molar mass constant, M u = 1×10−3 kg/mol = 1 g/mol:[3]M (H) = 1.007 97(7) × 1 g/mol = 1.007 97(7) g/mol M (S) = 32.065(5) ...
The rate of diffusion of gas (from Graham's diffusion law) is dependent on the square root value of the molar mass of the gas, the quotient expression for the rate of diffusion of a gas is: R∝1M, where, M is the molar mass or molecular weight measured in...
