Question

convert 5.6 grams of NO2 to grams of N2O4

does anyone know the answer?

Answer 1

hm you generally need an equation for the process, but since you're not changing any atoms, the mass stays the same.

note \(NO_2\) is 1 N and 2 O's, while \(N_2O_4\) is double the atoms, but the mass cant be more nor less.

Answer 2

yeah, so the amount of moles is decreasing by half, but the mass is constant.
