PLEASE HELP :"( DUE NOW!!
What is the equation for the equilibrium constant for this equation?

CO+3H2⇌CH4+H2O

[H2O][H2]/[CH4][CO]

[CO][H2]3/[CH4][H2O]

[CH4][H2O]/[CO][H2]3

[CH]4[H2O]/[H2]3

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

the answer would be a

a electronegativity decreases beacuse the size of nucleus is bigger.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
