Can someone explain to me why Beaker II has the greatest mole fraction of methanol? When I calculated this, I found that Beaker II made up 0.5 of the total moles in solutoon, same as Beaker i.

I think I get it, but for the MCAT, without doing the math, is it because the mass of methanol is less than that of ethanethanol in beakers 1 and 3 but more than the mass of ethanol in beaker 2, thus the mole fraction of methanol is greatest in beaker 2? We go by mass of methabol, and the next beaker with the greatest amount of methanol in relation to ethanol is beaker 1 where the ratio of mass of methanol to ethanol is 1:1, then beaker 3 had the smallest amount of mass of methanol because it only has 32 g while it has 46 g of Ethanol?
