How many moles are there in 8.50 X 1024 molecules of sodium sulfate, Na2SO3?
DiKsa [7]
Hello!

To solve this question, we need to use the Avogadro's Number, which is a constant first discovered by Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are 6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:

8,50* 10^{24}molecules* \frac{1 mol Na_2SO_3}{6,02* 10^{23}molecules}=14,12 molesNa_2SO_3

So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent 14,12 moles of Na₂SO₃ 

Have a nice day!

Scale-up is the term used to refer to the increase in the batch size of a product. This is only done after a drug has been proven successful against the target disease after extensive pilot studies.

Scale-up is the last operation carried out when a drug has passed through all stages. It is not included in preliminary preformulation studies

stepan [7]

Answer:

Skeletal system

Explanation:

The skeletal system is made up of all the bones, cartilage, and ligaments in the body. There are over 200 bones in the human skeleton, connected by joints which allow them to bend and rotate.

It protects the vital organs, gives our body form and structure, and allows us to move (or bust a move!)

To move, the skeletal system works with the muscles and nerves in the body.
