Molecular weight:在化学中,这个术语也常被用来描述每摩尔物质的质量。但严格来说,'molar mass'更常用于表示单一化合物的质量,'molecular weight'则可能用于描述更复杂的大分子,如蛋白质或DNA。 Gram molecular weight:这个术语也是描述每摩尔物质的质量,特别是在一些旧的化学文献中,但这个术语...
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...

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

When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. The atomic weights used on this site come from NIST, the National ...
molecular weight of a substance. With this method, molecular weight is calculated by measuring the mass of a known volume of a vaporized liquid. Because the concept of the mole had not been developed in Dumas’ era, he computed relative molecular weights based on relative gas densities. Though...
mass than one mole of hydrogen atoms. A dozen Boston Cream doughnuts would weigh more than a dozen glazed doughnuts even though there are twelve of each. The mass of one mole of particles of a substance is called its “molar mass” (sometimes called formula or molecular weight. One mole ...
