For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...
you can't really talk about them individually without it becoming really cumbersome. For that reason, scientists make use of the mole. It describes a huge number of molecules. Grams per mole thus describes the mass of an element when there are one mole particles of that substance. ...

Determine themolecular formulaof the molecule. Use the periodic table to determine theatomic massof each element in the molecule. Multiply each element'satomic massby the number of atoms of that element in the molecule. This number is represented by the subscript next to the element symbol in ...
The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents Where "n" number of equivalents is the quantity of charge depending on the substance. If the substance is an element, ion, acid, base, or ionic compound, it will determine "n". How is equivalent weigh...

the rest of the calculations is yours, I can write the whole process but the rules says that you have to try to solve the problem.when you will get an idea who to manage the rest of the problem reply and we will tell you if its OK:) Logged My name is Bond, Covalent Bond...
The molar mass of elements describes the mass of one mole of that element and is usually presented on the periodic table of elements. This can be used as a conversion factor to convert the mass of an element to the equivalent number of moles or vice versa. ...
Say you want to calculate the mass ratio of sulfuric acid, H2SO4. 1. Determine the Molar Mass of Each Element Present H2SO4contains hydrogen (H), sulfur (S) and oxygen (S). From the periodic table, you can see that the molar masses of these elements are: ...
