Okay, so an element Q exists in two states, 320Q and 319Q. It's overall atomic mass is 319.58 as it appears on a hypothetical periodic table. 319Q's atomic mass is 319.02 g/mol and 320Q's atomic mass is 320.04 g/mol. The 319.58 is composed of the average amount of the two per mol of Q. What are the molar fractions of 320Q and 319Q respectively?
Me and my friend have been trying to figure this out and he says it's done like this:
%320Q=320.04/(319.02+320.04) to get .5007980471 (5008%)
I say that's bullshit because by just plug 'n checking I get that Q320 should be closer to 55%
How is this type of problem done?
