Question

How many molecules are in 1 mol of sucrose (C12H22O11)?

Answer 1

Answer:

6.022 × 10²³ molecules of sucrose

Explanation:

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

For one mole sucrose:

342.3 g of sucrose = 1 mole of sucrose = 6.022 × 10²³ molecules of sucrose
