mass = moles × molar mass C. molar mass = moles × mass D. moles = mass + molar mass 相关知识点: 试题来源: 解析 B。本题考查物质的量、质量和摩尔质量的关系。物质的量等于质量除以摩尔质量,即 mass = moles × molar mass。选项 A、C、D 关系错误。
Atomic Mass and Molar Mass The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of the element, which is the mass of ...
The molar mass of a substance is the mass of one mole of that substance. What is the unit of molar mass? A. g/mol B. mol/g C. L/mol D. mol/L 相关知识点: 试题来源: 解析 A。本题考查摩尔质量的单位。摩尔质量是指单位物质的量的物质所具有的质量,单位是克每摩尔(g/mol)。选项 B...
What is the molar mass of KMnO4? Molar Mass: Molar mass is the number of grams of a substance that equals one mole or {eq}6.02 x 10^{23} {/eq} molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted by {eq}g/mol {/eq}...
What is the molar mass of lysozyme? Calculating Molar Mass for a Large Molecule: Lysozyme, an enzyme (protein), is a large molecule that is found in tears and egg whites. It functions as part of the immune system, and it serves as an antibiotic as it breaks down the cell walls of ba...
Molecular mass is also called molecular weight. Because the mass is relative to carbon-12, it's more correct to call the value "relative molecular mass". A related term is molar mass, which is the mass of 1 mol of a sample. Molar mass is given in units of grams. ...
Furthermore, NMR H/D exchange data and molecular dynamics simulation results suggest that the protofibril core region tends to unpack at the early stage of 3D domain swapping, so that the amyloid fibrillation can proceed during the 3D domain swapping process. We propose that 3D domain swapping ...
Circular dichroism (CD) spectra were acquired on a Jasco J-810 spectropolarimeter (Jasco Inc., Easton, MD) located at the UBC Laboratory for Molecular Biophysics. Far-UV CD spectra were recorded between 190 and 250 nm using a scan speed of 100 nm/min, a response time of 2 s and a ban...
What is the molar mass of a compound if 0.372 mole of it has a mass of 152g?A. 2.44 ×10 -3 B. 56.544 C. 408.602 D. uncertainty 如何将EXCEL生成题库手机刷题 如何制作自己的在线小题库 > 手机使用 分享 复制链接 新浪微博 分享QQ 微信扫一扫 微信内点击右上角“…”即可分享 反馈 收藏 ...
Gram Molecular Mass: The gram molecular mass is the same idea as the molar mass of a substance. The periodic table lists all of the elements' molar masses. It is the average of all of the isotopes of that element. Answer and Explanation:1 ...
