If 4.9 kg of CO2 are produced during a combustion reaction, how many molecules of CO2 would be produced?

Considering the definition of avogadro's number, 6.707×10²⁵ molecules of CO₂ would be produced.

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.

Avogadro's number applies to any substance.

First, you must know the number of moles that contain 4.9 kg= 4900 g (being 1 kg=1000 g) of CO₂. For that, you must know that the molar mass of CO2, that is, the mass that contains one mole of the compound, is 44 g/mole.

Then, the number of moles of CO₂ can be calculated as:

So, you can apply the following rule of three: if by definition of Avogadro's Number 6.023×10²³ molecules are contained in 1 mole of CO₂, then how many molecules of CO₂ are composed of 111.36 moles?

amount of molecules of CO₂= (6.023×10²³ molecules × 111.36 moles)÷ 1 mole

amount of molecules of CO₂= 6.707×10²⁵ molecules

Finally, 6.707×10²⁵ molecules of CO₂ would be produced.

Explanation:

Given parameters

Mass of CO₂  = 4.9kg  = 4900g

Unknown:

Number of molecules  = ?

Solution:

To find the number of molecules, we need to find the number of moles first.

 Number of moles  =

          Molar mass of CO₂  = 12 + 2(16)  = 44g/mol

   Number of moles  =  = 111.36mole

A mole of substance is the quantity of substance that contains the avogadro's number of particles.

       1 mole  = 6.02 x 10²³molecules

     111.36 moles  =   111.36 x 6.02 x 10²³molecules   = 6.7 x 10²⁶molecules

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
