To find the mass of a one mole of a specific molecule, add the atomic masses of each of its component atoms. You can look these up in the periodic table.
In chemistry, mass ratio, often called "percent composition by mass," is the proportion of a particular molecule that consists of each that molecule's constituent elements. For example, water consists of 11.1 percent hydrogen (H) and 88.9 percent oxygen (O), meaning that a 1,000-gram sample...
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 ...
The molar mass is: 23 + 16 + 1.008 = 40.008 g Thus, the equivalent weight is 40.008g/1 or 40.008 g/equivalent. What is the difference between equivalent weight and molecular weight? Molecular weight is the total atomic mass of a molecule for a compound. Equivalent weight, on the other...
To get the molar mass of a molecule, or the mass of 1 mol of those molecules, simply add the individual masses of the atoms, being sure to account for subscripts. So for a water molecule, H2O, you would add the mass of 1 mol O (15.999 g) to the mass of 2 mol H (2 × 1.008...
Add these values together for each differentatomin the molecule. The total will be the molecular mass of the compound. Example of Simple Molecular Mass Calculation For example, to find the molecular mass of NH3, the first step is to look up the atomic masses of nitrogen (N) and hydrogen ...
Sometimes you're given a value inmolesand need to convert it to grams. To do this, first calculate the molar mass of a sample. Then, multiply it by the number of moles to get an answer in grams: grams of sample = (molar mass) x (moles) ...

To calculate a milliequivalent (mEq) you have to have two pieces of information: The mass of the substance in question and the molar mass (or molecular weight) of that substance. You must also be able to identify its valence from its molecular formula, a
