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
