if air is made up of only 2gases oxygen and nitrogen, and the molecular mass of air is 29g/mol, find the % of each component in the air,
what i thought i should do is make 2 equations,
Mw(O)=16
Mw(N)=14
X*16 + Y*14 = 29 (in 1mol of air)
X + Y = 1
but the solution to this is not possible, i get one as a negative pct
the correct answer is meant to be
72.5%
27.5%
