精确质量:57.95860 摩尔质量:单位物质的量的物质所具有的质量称摩尔质量(molar mass),用符号M表示。当物质的量以mol为单位时,摩尔质量的单位为g/mol,在数上等于该物质的原子质量或分子质量。对于某一化合物来说,它的摩尔质量是固定不变的。而物质的质量则随着物质的量不同而发生变化。本文仅代表作者观点,不代表...

"Molecular weight", "molecular mass", or "molar mass" are commonly used to describe the size of a molecule. They are the sum of atomic masses in terms of atomic mass unit (u or g/mol) of individual atoms that make up the molecule.Answer and Explanation: The molecular weight of ...
The molar mass of a substance, similar to density, serves to convert between two different physical measurements of matter. The molar mass can serve as a conversion factor between the mass of a substance and its amount in moles. Molar mass is typically expressed in units of grams per mole....
NaCl 的摩尔质量为 58.44 g/mol。2.计算 NaCl 的摩尔数：由于称取了纯 NaCl 加入水中溶解，因此溶液中的 NaCl 的摩尔数为：moles of NaCl = mass of NaCl / molar mass of NaCl = 0.1169 g / 58.44 g/mol = 0.002001 mol 3.根据反应方程计算 AgNO3 的摩尔数：根据反应方程，1 mol ...

There is no "molar" for a dry solid, if I take the sense in which you mean it. It has no "molarity" because its not a solution of any concentration, which is how molarity I defined. It does have a molar mass, which you can look up or compute to make a solution I a certain ...
