A mixture contains 4.1 moles of H_2+, 1.3 moles of He and some O_2. If the mole fraction of O_2 is .3166, how many moles of O2 are in the mixture?
*** In this problem it doesn't specify how much O_2. Can you help me set up this equation and how to solve it? Thanks

Some word problems in this chapter involve one "easy equation", usually found by translating a simple relationship between x and y (like one is twice the other or that they add to a given number). The second linear equation often uses a "rate times quantity formula. This is true for • distance problems (rate.time = distance) • mixture problems (percent concentration amount of solution - amount of concentrate) money problems (value of one item. how many items...
