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...
The abbreviation commonly used for molecular weight is MW. The molar mass is the mass in grams of 1 mole of the substance. Molar masses (in grams) are therefore numerically equal to formula weights (in amu). In the example we've been using, this tells us that because the FW of ...
What is the molar mass of Mg?Molar Mass:Molar mass is the weight of one mol of a substance. It typically has units of grams per mol (g/mol). Every element or chemical has a particular molar mass that is determined by the weight of each element involved....

The Molar mass of an element is the mass in grams of 1 mole of the element. It is determined by taking the atomic weight of the element on the periodic as g/mol. The molar mass of aluminium is 26.982 g/mol Was this answer helpful? 2Similar Questions Q1 What is the molar mass of ...
where [micro] (Pa x s or kg/(m x s)) is the kinetic viscosity of gas, P (Pa) is the pressure, and M (kg/mol) is the molar mass. Relevant parameters of material IG-110 and BC, which are acquired by mercury intrusion porosimetry (MIP), are shown in Table 2. Moisture Transfer...
What is the molar mass of gas that, at STP, has a volume of 100ml and a mass of 0.125g? Molar Mass of a Gas: We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but ...
According to the definition of the mole, 12 g of 12C contains 1 mole of 12C atoms (its molar mass is 12 g/mol). This relationship holds for all elements, since their atomic masses are measured relative to that of the amu-reference substance, 12C. Extending this principle, the molar ...

it is possible to determine the value of any of the four variables knowing the other three. Mass can even be used as one of the variables since it has a relationship with moles. The molar mass and density of a gas can be determined from the ideal gas law. ...
