Respuesta :

N2O4

We know this:

Molecular weight of N2O4 = 92.0 g/mol

N2O4 contains in it 2 atoms of N.

-------------------------------------------------------------------------

So,

92.0 g of N2O4 ---------------- 2 atoms of N

x ---------------- 1.00x10^12 atoms of N

x = ( 1.00x10^12 atoms x 92.0 g ) / 2 atoms = 4.6x10^13 g of N2O4

-------------------------------------------------------------------------

Answer: 4.60x10^13 g of N2O4
