The molecular weight (or, more appropriately, the molar mass) is defined by # of grams per # of moles.
MW = g / mol
For example: if you have 4 grams of substance and you know the substance to be 2 moles (say, for example, the balanced chemical equation), then your MW would be 2.

What is the molar amount?
The molar amount refers to the number of moles of a substance present in a given sample. It is calculated by dividing the mass of the substance by its molar mass. Molar amount is typically expressed in moles.
Is molar mass is mass in grams of one kilogram of any pure substance?
No, molar mass is the mass in grams of one mole of a substance. One mole is equal to the molecular weight of the substance in grams.
What is the substance that has formula mass of 133.5 amu?
The substance with a formula mass of 133.5 amu could be chloroform (CHCl3), which has a molar mass of 119.37 g/mol. The molar mass of any substance is equal to its formula mass in amu.
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
What is the molar mass of a molecule?
The mass of one mole of substance, usually in grams or kilograms
What is the molar mass of a substance in daltons?
The molar mass of a substance in daltons is the mass of one mole of that substance, measured in daltons.
What is molar mass of iron?
The molar mass of iron is 55.845g per mol. Molar mass is the mass of a given substance divided by its amount of substance.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
How can one determine the amount of moles in a given substance?
To determine the amount of moles in a substance, you can use the substance's mass and molar mass. Divide the mass of the substance by its molar mass to calculate the number of moles. This formula is represented as moles mass / molar mass.
What is the relationship between the molar mass and density of a substance?
The relationship between the molar mass and density of a substance is that the molar mass affects the density of a substance. Generally, substances with higher molar masses tend to have higher densities. This is because the molar mass represents the mass of one mole of a substance, and denser substances have more mass packed into a given volume.
Which term is used to represent the mass of 1 mole of molecules of a substance?
This is equal to the molar mass of this substance.
What is the relationship between the molar mass of a substance and its equivalent in daltons?
The molar mass of a substance is equal to its equivalent in daltons.
The mass of a mole of a substance expressed in grams is called a?
The mass of a mole of a substance expressed in grams is called the molar mass. This value is numerically equal to the atomic or molecular weight of the substance and is expressed in units of grams per mole.
What is molar atomic mass?
The atomic (molecular) weight of a substance is its molar mass.
What affect would an incorrect reading of temperature have on the molar mass?
An incorrect reading of temperature would not directly affect the molar mass of a substance. Molar mass is a fixed property of a substance regardless of the temperature at which it is measured. Temperature typically affects the physical state and behavior of the substance, but not its molar mass.
What is the molar mass of the substance in da unit to g/mol?
The molar mass of a substance is the mass of one mole of that substance, measured in grams per mole (g/mol).
What is the molar mass of a substance in amu grams per mole?
The molar mass of a substance is the mass of one mole of that substance, measured in atomic mass units (amu) or grams per mole.
