The number of molecules of Nitrogen dioxide : = 4.816 x 10²⁴

Further explanation

Given

4 moles of Oxygen(O2)

Required

The number of molecules

Solution

Reaction

2NO + O2 ⇒ 2NO2

From the equation, mol NO2 :

= 2/1 x mol O2

= 2/1 x 4 moles

= 8 moles

The number of molecules :

= 8 x 6.02 x 10²³

= 4.816 x 10²⁴
