A gas mixture contains 12.2 g of N2,5.00 g of H2, and 7.10 g of CH4. What is the mole fraction of CH, in the mixture?
A gas mixture contains 13.2 mol of NO and 5.55 mol of Br2. (a) Compute the mole fraction of NO in the mixture. XNO = (b) The mixture is then allowed to stand, and the NO starts to react with the Br2 to give NOBr: 2NO(g) + Br2(g) 2NOBr(g) At a certain point in the reaction, 2.40 mol of NOBr is present. Determine the mole fraction of NO in the new mixture. XNO =
A gas mixture consists of N2, O2, and Ne, where the mole fraction of N2 is 0.55 and the mole fraction of Ne is 0.25. If the mixture is at STP in a 5.0 L container, how many molecules of O2 are present?
Mole fraction of O2 = 571 Correct The mole fraction is the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture. The mole fractions can be represented in terms of pressures The total pressure PTOTAL = 0.180 atm +0.240 atm = 0.420 atm The mole fraction of CH4 in the mixture PCH 0.180 atm 0.420 atm = 0.429 PTOTAL Since it is the mixture of two gases,...
