Convert moles C2H5OH to grams - Conversion of …

WebWe also know that the same number of moles of any gas occupies the same volume (i.e. 1 mole of any gas occupies 24.0dm3 at room temperature and pressure), so the % by volume gas A is its mole fraction x 100. e.g. in air we have 78% nitrogen, so x(N 2) = 0.78. A typical air pressure would be 100kPa, ) 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 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams.
