Converting Molecules to Moles Using Avogadro's Number

How do you convert 308 molecules of MnO₄ to moles of MnO₄?

Given data: 308 molecules MnO₄

Answer:

51.15 × 10²³ moles of MnO₄

Explanation:

Given data:

Number of molecules of MnO₄ = 308 molecules

Number of moles of MnO₄ = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms, ions, and molecules in one gram atom of an element, one gram molecule of a compound, and one gram ion of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For 308 molecules of MnO₄:

308 molecules of MnO₄ × 1 mole / 6.022 × 10²³ molecules of MnO₄ = 51.15 × 10²³ moles of MnO₄

Final answer:

To convert from molecules of MnO₄ to moles of MnO₄, you can use Avogadro's number. Given 308 molecules of MnO₄, you can calculate that it is equal to 51.15 × 10²³ moles of MnO₄.

Explanation:

The question is asking about the conversion from molecules of MnO₄ to moles of MnO₄. In chemistry, the unit mole is used to measure the amount of a substance. It is defined as the amount of a substance that contains as many entities as there are atoms in 12 grams of carbon-12. One mole of any substance contains Avogadro's number of entities, which is approximately 6.022 x 10^23.

To convert from molecules to moles, you can use Avogadro's number. For example:

Given that there are 308 molecules of MnO₄, we can use the following conversion factor:

1 mole of MnO₄ = 6.022 x 10^23 molecules of MnO₄

Therefore, to convert 308 molecules of MnO₄ to moles, we can use the following calculation:

308 molecules MnO₄ * (1 mole MnO₄ / 6.022 x 10^23 molecules MnO₄) = 51.15 × 10²³ moles MnO₄
