Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
In the second question, the Ideal Gas Law is used to find the number of moles of a compound, which is then used to calculate its molecular weight. By finding the weights of carbon, hydrogen, and oxygen in the compound, the molar ratio can be determined to find the molecular formula. ...
To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. You then calculate molarity by measuring the volume of the solution...
To calculate the average atomic mass of chlorine, use the information in a periodic table of the element (see Resources) to find the (weighted) average but changing the percents to decimals: (34.969×0.7577)+(36.966×0.2423)=35.45amu(34.969×0.7577)+(36.966×0.2423)=...

needed to eject an electron from the surface of a metal. is it possible to calculate this energy from the atomic properties of the metal (atomic number, atomic mass, electron configuration, etc.), and the properties of the lattice structure, in a way that doesn't require a complex ...
Themolecular massor molecular weight is the total mass of a compound. It is equal to the sum of the individual atomic masses of each atom in the molecule. It's easy to find themolecular massof a compound with these steps: Determine themolecular formulaof the molecule. ...
