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?

There are 3.01x10²³ molecules of sucrose

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

Hope this helps

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

i have no clue hope you find the answer
