How many miles are there in 3.011 x 1023 molecules of N2O4

0.5 moles

Explanation:

Given dа ta:

Number of moles of N₂O₄ = ?

Number of molecules = 3.011 * 10²³ molecules

Solution:

The given problem will solve 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.

For example,

18 g of water = 1 mole = 6.022 * 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 * 10²³ atoms of hydrogen

Number of moles in 3.011 * 10²³ molecules of N₂O₄.

3.011 * 10²³ molecules * 1 mol / 6.022 * 10²³ molecules

0.5 moles
