How many molecules of no2 are produced when 2.0 × 1020 molecules of n2o4 are decomposed according to the following equation? n2o4(g) → 2no2(g) 2.0 × 1020 1.0 × 1020 4 4.0 × 1020

- molecules.

Solution:- The given balanced equation is:

From the balanced equation, 1 molecule of the reactant gives two molecules of the product. So, the number of molecules of the products formed will be two times the molecules of the reactant.

=

So, the last choice is the correct one.

okay yes , aha.
