WebApr 7, 2024 · x A = Mole fraction of the gas 'A' over the surface of solution k H = Henry's law of the gas The Henry's Law constant for the solubility of N 2 gas in water at 298 K is 1 ⋅ 0 × 1 0 5 atm. The mole fraction of N 2 in air is 0.8. What is the number of moles of N 2 from air dissolved in 10 moles of water at 298 K and 5 atm pressure ? WebAnswer: 4.2 mol H2SO4 Part c. From the balanced chemical equation above, we can see that 1 mole of Al reacts with 1/2 mole of H2. Therefore, to determine the number of moles of H2 formed by the complete reaction of 0.325 mol of Al, we can use the following calculation: 0.325 mol Al × (1/2 mol H2 / 1 mol Al) = 0.163 mol H2 Answer: 0.163 mol H2 nutrition facts egg mcmuffin
