How many molecules are in CO²

53.11× 10²³ molecules

Explanation:

Given data:

Number of molecules of CO₂ = ?

Mass of CO₂ = 388.1 g

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of CO₂ = 12× 1 + 16×2

Molar mass of CO₂ = 44 g/mol

Now we will put the values in formula.

Number of moles = 388.1 g/ 44 g/mol

Number of moles = 8.82 moles

Now we will calculate the number of molecules by using 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

8.82 mol × 6.022 × 10²³ molecules / 1 mol

53.11× 10²³ molecules

Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present.

Explanation:

We know the molar mass of CO2(g) is 44.01⋅g⋅mol−1 . And so Avogadro's number of carbon dioxide molecules have this mass... And we take the product of the quotient... Molecules of carbon dioxide=5.00⋅mol×6.022×1023⋅mol−1≅30×1023⋅carbon dioxide molecules.

answer: your mm

explanation:

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
