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...
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。反馈 收藏 ...
Molar mass is the mass of one mole of a substance. A mole is defined as the number of atoms in 12 grams of thecarbon-12isotope. This is always a fixed number, known as Avogadro's number. Therefore, the molar mass of a substance is the mass of Avogadro's number molecules of that s...
