if the molecular weight of a substance represents the number of grams required for 1 mole, then the number of moles represented by any given amount of substance will be equal to the grams of that substance divided by its molecular weight. Mathematically, this is represented by moles = grams ...
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles. When dividing by two units that both use grams in their measurement ...

Let the solubility of CaC₂O₄ in moles per liter be S. From the dissociation:- The concentration of Ca2+ ions will be S.- The concentration of C2O2−4 ions will be 2S. Step 4: Substitute into the Ksp expressionSubstituting these into the Ksp expression gives:Ksp=S⋅(2S)2=S...
# of moles = weight (g)/ molecular weight (g) Molarity is the unit used to describe the number of moles of a chemical or compounds in one liter (L) of solution and is thus a unit of concentration. By this definition, a 1.0 Molar (1.0 M) solution is equivalent to one formula weigh...
chemical from the manufacturer's information, such as the Material Safety Data Sheet (MSDS). This calculation provides you with the grams of chemical in 1 liter of solution. In the above example, you would multiply 2.50 moles by 74.55 g/mole (the molecular weight of KCl) to obtain 186.4 ...
