how many molecules of nitrogen dioxide are there in 2.00 moles of nitrogen dioxide ? Show steps please!

2 moles of NO₂ contain 12.044 × 10²³ molecules  of NO₂

Explanation:

Given data:

Number of moles of NO₂ = 2.00 mol

Number of molecules of NO₂ = ?

Solution:

It will be solve through Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

2.00 mole NO₂  × 6.022 × 10²³ molecules  of NO₂  / 1 mol of NO₂

12.044 × 10²³ molecules  of NO₂

Thus, 2 moles of NO₂  contain 12.044 × 10²³ molecules  of NO₂ .

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

i think its 100

i hope this !
