1.	A gaseous mixture contains 4.0g of H2 and 56.0g of N2. The mole fraction of H2 in the mixture is
Answer» GIVEN:⇒ A gaseous mixture contains 4.0 g of H₂ and 56.0 g of N₂ To FIND:⇒ The mole fraction of H₂ in the mixture Solution:We know that,Mole Fraction (χ)Mole fraction is defined as the number of moles of a component divided by the TOTAL number of moles of a mixtureMole (n)Given,A gaseous mixture contains 4.0 g of H₂ and 56.0 g of N₂Given Mass of H₂ = 4 gGiven Mass of N₂ = 56 gMolar Mass H₂ = 2 gMolar Mass N₂ = 28 gAccording to the Question,We are asked to find THETHE mole fraction of H₂ in the mixtureTherefore,Hence,The mole fraction of H₂ in the mixture is 0.5
