Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
A chemical equation demonstrates the quantity of atoms of every component that make up the compound. The atomic proportion of components in the compound is the same as the molar proportion of those components. This information can be applied to solve for the mass of one mole of a compound by...

Plugging this into the equation gives: q=5molHg(27.8Jmol∗K)(10K) So the amount of heat required to heat 5 mol of Hg by 10 K is: q=1390J You can also make use of this equation to find the number of mols of a substance if you know how much heat was absorbed. For example:...
The weight average molar mass, Mw, is the number of chains of given weight times the weight of material with that given molar mass divided by the total weight of polymer. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 ...
