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):
WebSep 21, 2024 · molar mass = 1.211 g 0.0275 mol = 44.0 g/mol Since N has a molar mass of 14 g/mol and O has a molar mass of 16 g/mol, the formula N 2 O would produce the correct molar mass. Step 3: Think about your result. The R value that corresponds to a pressure in atm was chosen for this problem. 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 …
