WebSep 21, 2024 · n = P V R T = 0.987 atm × 0.677 L 0.08206 L ⋅ atm/K ⋅ mol × 296 K = 0.0275 mol Now divide g by mol to get the molar mass. 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. WebApr 9, 2024 · Solution: From the given molecular formula it is clear that the given chemical substance has 2 iron atoms and 3 oxygen atoms. Now, the atomic weights of iron and oxygen atoms are 55.847 amu and 15.9994 amu respectively. Thus, the molecular weight of Fe2O3 is = 2* (atomic weight of iron) + 3* (atomic weight of oxygen) = 159.692 amu.
