Well I am new to this forum, but I do have one question... What is the difference between molecular mass and formula unit mass. My text says: The average mass of one molecule of a compound in atomic mass unit is called molecular mass. The sum of the atomic masses of all the atoms...
in other words, the molar mass is the total mass of all the atoms in grams that make a mole of a particular molecule. therefore, the units of molar mass are grams/mole. how to find the molar mass of a compound? step 1. make use of the chemical formula to determine the number ...
例如：molar mass of CO2 = 44 g/mol； molar mass of NaCl = 58.5 g/mol 简单来说，只有 molar mass 的 unit 是 g/mol，而其他都是没有 unit 的 relative mass。以 H2SO4 为例（Pure H2SO4 is molecular）： Relative atomic mass of H = 1 Relative atomic mass of S = 32 Rela...
Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
Molecular weight = thesumof (# of molecules of each elementtimesthe atomic weight of that element) for each element What is the meaning of molecular weight? Themolecular weightof a molecule is the weight of one molecule. To find the molecular weight, add the weights of each individual atom ...
