区别:molecular weight的意思是:分子质量,相对分子质量 molar mass 的意思是:摩尔质量,是指单位物质的量的物质所具有的质量,用符号M表示。molecular weight 短语:numerical molecular average weight 数均分子量 molecular-weight distrbution 分子量分布 Molecular Molecular structure weight 分子式 例句...
第一个是求摩尔质量 就相当于原子量 h2 2g/mol cl2 71g/mol br2 160g/mol n2o4 92g/mol na2s 78g/mol,你是不是题目抄错了nh3 17g/mol k2so4 174g/mol,第二个是算有多少摩尔 质量/摩尔质量 10gh 5mol 50gcl2 0.704mol 100gbr 0.625mol 20gna2s 0.256mol 第三个是算有多少克 摩尔...
摩尔质量 单位是g/mol。比如水的molecular weight:18 molar mass:18g/mol.结果一 题目 molecular weight and molar mass 有什么区别吗?可以举个例子来看看吗?_(:3」∠)_生物化学领域的 答案 分子质量(相对分子量)单位是“1”摩尔质量 单位是g/mol。比如水的molecular weight:18 molar mass:18g/mol. 结果二...
以 H2SO4 为例(Pure H2SO4 is molecular): Relative atomic mass of H = 1 Relative atomic mass of S = 32 Relative atomic mass of O = 16 Relative molecular mass of H2SO4 = 98 Formula mass of H2SO4 = 98 Molar mass of H2SO4 = 98 g/mol其实只是对于不同结构的原子/化合...

CHEMISTRY GLOSSARY molar mass molarna masa Molar mass is the mass of one mole of a substance. M= mn It is normally expressed in units of g mol-1, in which case its numerical value is identical with the relative molecular mass.
Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m
