WebFirst, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 … WebDensity and molar mass are calculated by modifying the ideal gas law equation. What we do is first replace the moles (n) in PV = nRT with mass over the molar mass: n ( m o l e s) = m ( m a s s) M ( m o l a r m a s s) Next, we rearrange this formula to bring the V under the m which is the density of the gas (mass/volume = density):
WebJun 18, 2024 · The molar mass of an element is found on the periodic table, and it is the element's atomic weight in grams/mole (g/mol). If the mass of a substance is known, the number of moles in the substance can be calculated.
