Question

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

Answer 1

Answer:

0.5 moles

Explanation:

Given data:

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
