How many molecules of nitrogen dioxide (NO2) can be produced from 4 moles
of oxygen (O2)? *

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

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

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
