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.
How many moles of O2 are required for the complete combustion of 2.2 g ...
WebCorrect option is B) Oxygen ⇒ molar mass = 16g =1 mole of O 2. Then, 2g of oxygen = 162 moles of O 2. Solphur ⇒ Molar mass =32 g = 1 mole of sulphur. Then 4g of sulphur = 324×1 mole of sulphur. 0.125 ,moles of oxygen and 0.125 mole of sulphur contains same number of atoms as 1 mole of any gashas 6.023×10 23 atoms. Web3 apr. 2016 · Chemistry The Mole Concept The Mole 1 Answer anor277 Apr 3, 2016 In 1 mol O2 gas, by definition you have Avogadro's number of MOLECULES. Explanation: … no reply sage online payslips
How many molecules are in 2g of O2? - Brainly.com
Web22 feb. 2024 · Explanation: Well, we first write down the balanced equation, that is 2SO2(g) + O2(g) → 2SO3(g) From here, we can see that the mole ratio between SO2 and SO3 is 2:2 = 1. That means, for every mole of sulfur dioxide (SO2) used, one mole of sulfur trioxide (SO3) will be produced. WebThe molar volume of an ideal gas at standard temperature and pressure (273.15 K, 101.325 kPa) is 22.413 962 x 10-3 m3 mol-1 with a standard uncertainty of 0.000013 x 10-3 m3 mol-1 2. The calculator below uses the formula to convert liters to moles and to convert moles to liters, where is 22.413962. Web4 aug. 2024 · volume of O 2 Step 2: Calculate. 4.96 mol × 22.4 L/mol = 111.1 L Step 3: Think about your result. The volume seems correct given the number of moles.
