WHAT MASS OF THE SECOND ELEMENT REACTED? hOW TO i GO ABOUT SOLVING THIS PROBLEM? How many moles of iron are in the nail?Ī 40.0g SAMPLE OF AN ELEMENT COMBINES COMPLETELY WITH ANOTHER ELEMENT TO MAKE 112.2 OF A COMPOUND. a) An element composed of atoms b) An element composed of diatomic molecules c) An ionic compound d) Made from more than one type of atom 2. in certain compound of copper and oxygen, Cux Oy, we find that a sample weighing 0.5424g contains 0.4831g Cu. If one can find the ratio of the number of moles of the elements in a compound to one another, one can find the formula of the compound. 347 moles of an element has a mass of 39.00 g. “Why Is Molar Mass Important?” Sciencing. “What Is Molecular Weight?

They are physical properties of substances and are very useful in chemical analysis techniques. Although the definition and units are different for molar mass and molecular weight, the value is the same. The main difference between molar mass and molecular weight is that molar mass gives the mass of a mole of a particular substance whereas molecular weight is the mass of a molecule of a particular substance. Molecular Weight:Molecular weight is calculated as the mass of substance relative to the 1/12 th of the mass of carbon-12 atom. Molar Mass: Molar mass is calculated by dividing the mass of a substance by the amount of the substance. Molecular Weight:The molecular weight is unitless but is given as amu (or atomic mass units). Molar Mass: The unit of molar mass is kgmol-1 (or kg/mol). Molecular Weight:The term molecular weight can be defined as the mass of a molecule. Molar Mass: Molar mass is the mass of a mole of a particular substance. Difference Between Molar Mass and Molecular Weight Definition The molar mass of phosphine is 33.99758 g/mol. This indicates that both molar mass and molecular mass are same in their values but are different in their units.įigure 1: Phosphine.

But in general, it is given in the unit gmol -1 or g/mol. The SI unit for molar mass is kgmol -1 or kg/mol. The molar mass is obtained by dividing the mass of a particular substance by the amount of it. Molar mass is the mass of a mole of a particular substance. Key Terms: Atoms, Carbon, Isotope, Molar Mass, Mole, Molecular Weight What is the difference between Molar Mass And Molecular Weight – Definition, Formula, Units, Calculationģ.

Molar mass and molecular weight are two such physical properties of substances. Therefore, it is very important to understand the chemical and physical properties of molecules in order to conduct chemical reactions and predict the final products. Almost all chemical reactions are involved the changes occur in molecules or compounds. These molecules can get attached to each other to form compounds. Molecules are substances formed due to combinations of same or different atoms in different ratios. Main Difference – Molar Mass vs Molecular Weight
