O gás oxigênio necessário a respiração para a síntese de glicose pode ser em certas condições explicado pelo modelo de gás ideal

. Em 64g de gás oxigênio estão num cilindro de mergulho. Determine o número de mol de gás oxigênio: (Considerando que o número de Avogadro é 6,0 x 10^23 e a massa de gás oxigênio - O2 = 32g)

Answer:

Em 64 g de gás oxigênio no cilindro de mergulho, existem 2 moles de gás oxigênio e (1,20 × 10²⁴) moléculas de gás oxigênio.

In 64 g of Oxygen gas in the diving cylinder, there are 2 moles of Oxygen gas and (1.20 × 10²⁴) molecules of Oxygen gas.

Explanation:

O número de moles de um elemento é dado como

Número de moles = (Massa / Massa molar) Massa de gás oxigênio no cilindro de mergulho = 64 g

Massa molar de oxigênio gás = 32.0 g / mol

Número de moles de gás oxigênio no cilindro de mergulho = (64/32) = 2 moles

O número de moléculas em 1 mole de qualquer substância = (6,0 × 10²³)

O número de moléculas em 2 moles de oxigênio no cilindro de mergulho = 2 × (6,0 × 10²³) = 12,0 × 10²³ = (1,20 × 10²⁴) moléculas

Espero que isto ajude!!!

English Translation

The number of moles of an element is given as

Number of moles = (Mass/Molar Mass)

Mass of Oxygen gas in the diving cylinder = 64 g

Molar Mass of Oxygen gas = 32.0 g/mol

Number of moles of Oxygen gas in the diving cylinder = (64/32) = 2 moles

The number of molecules in 1 moles of any substance = (6.0 × 10²³)

The number of molecules in 2 moles of Oxygen in the diving cylinder = 2 × (6.0 × 10²³)

= 12.0 × 10²³ = (1.20 × 10²⁴) molecules

Hope this Helps!!!

Answer:

No. of Molecules = 18.06 x 10²³ molecules

No. of Atoms of P = 3 atoms

No. of Atoms of Na = 9 atoms

Total No. of Atoms = 24 atoms

Explanation:

<u>FOR NUMBER OF MOLECULES</u>:

No.\ of\ Molecules = (No.\ of\ Moles)(Avigadro's\ Number)\\No.\ of\ Molecules = (3)(6.02\ x\ 10^{23}\ molecules})\\

<u>No. of Molecules = 18.06 x 10²³ molecules</u>

<u></u>

<u>FOR NUMBER OF P ATOMS</u>:

No.\ of\ Atoms\ of\ P = (No.\ of\ Moles)(N.\ of atoms of P)\\No.\ of\ Atoms\ of\ P = (3)(1\ atom})

<u>No. of Atoms of P = 3 atoms</u>

<u></u>

<u>FOR NUMBER OF Na ATOMS</u>:

No.\ of\ Atoms\ of\ Na = (No.\ of\ Moles)(N.\ of atoms of Na)\\No.\ of\ Atoms\ of\ Na = (3)(3\ atom})

<u>No. of Atoms of Na = 9 atoms</u>

<u></u>

<u>FOR TOTAL NUMBER OF ATOMS</u>:

Total\ No.\ of\ Atoms = (No.\ of\ Moles)(N.\ of\ atoms\ of\ Na + No.\ of\ atoms\ of\ P + No.\ of\ atoms\ of\ O)\\ Total\ No.\ of\ Atoms\ = (3)(3\ atoms + 1\ atom + 4\ atoms}) = (3)(8\ atoms)

<u>Total No. of Atoms = 24 atoms</u>

<u></u>
