How many moles do i have in 2g of o2

Webtherefore oxygen mols=2g/16 oxygen mol=0.125 mol then Hydrogen mols=12g/1 hydrogen mol=12mol So the limiting reactant is oxygen 2H+1 O provides one H2O molecule. So Oxygen reacts completely. Therefore 0.125*2 mol of Hydrogen reacts with one Oxygen Only one water molecule is formed. 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.
