Question

The sucrose molecule is a large and complex molecule built of carbon, hydrogen, and oxygen. How many sucrose

molecules are in 0.5 moles of sucrose?

Answer 1

There are 3.01x10²³ molecules of sucrose

Step-by-step explanation:

In order to calculate the number of molecules of any atom or compound, we need to use the Avogadro number which is 6.02x10²³. This number could represent atoms or molecules of any mole of compound or atom.

In other words, 1 mole of a certain atom or compound has 6.02x10²³ molecules or atoms.

we have 0.5 moles of sucrose, all we just need to do is a simple rule of 3:

If 1 mole contains 6.02x10²³ molecules

then 0.5 moles will contain:

n° molecules = 0.5 * 6.02x10²³ / 1

n° molecules = 3.01x10²³ molecules of sucrose

Hope this helps
