Calculate the number of oxygen atoms in a 50.0 sample of dinitrogen tetroxide . Be sure your answer has a unit symbol if necessa
GenaCL600 [577]

Answer:1.309 x 10^24 oxygen atoms

Explanation:

Molar mass of N2O4,=  2 x Molar mass of Nitrogen + 4 x Molar mass of Oxygen

= 2 x 14.01 + 4 x 16.0

= 92.02 g/mol

One mole of a substance is equal to 6.022 × 10²³ unit/ atoms/ molecules

In N2O4, there are 4  moles of Oxygen

if 92.02 g contains = 4 x 6.022 x 10 ^23 molecules

50.0 g wll contain=  (4 x 6.022 x 10 ^23  x 50)/ 92.02g

1.309 x 10^24 oxygen atoms
