How many moles of dinitrogen tetroxide (N2O4) are in 6.49 x 109 particles? 1.08 x 10–14 mol N2O4

3.091 x 1033 mol N2O4

6.02 x 1023 mol N2O4

1.08 x 10–23 mol N2O4

1.08 × 10⁻¹⁴ moles of N2O4

Explanation:

Given data:

Moles of dinitrogen tetroxide = ?

Number of particles = 6.49×10⁹

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions , particles 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 contain 6.022 × 10²³ particles.

6.49×10⁹ particles × 1 mole / 6.022 × 10²³ particles

1.08 × 10⁻¹⁴ mol

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

hope this !

and sorry if i'm late. have a good rest of your day! : d
