WebThe procedure to use the grams to moles calculator is as follows: Step 1: Enter the mass and formula weight in the input field. Step 2: Now click the button “Solve” to get the … 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 … WebStep 1/1. 1) The given reaction is: 2 N 2 + O 2 → 2 N 2 O Δ H = + 82.1 k J m o l. From the balanced reaction we know that, 2 moles of N2 absorbs 82.1kJ/mol of energy. Molar mass of N2 = 28 g /mol. so, 2 × 28 g/mol of N2 absorbs 82.1kJ/mol of energy. 56g/mol of N2 absorbs 82.1kJ/mol of energy. So, 94 g of N2 will absorb heat : 7 goals of financial managers
