If a sample of pure silver (ag) contains 3.35 x 1022 atoms of silver, how many moles of silver are in the sample?

The given number of silver atoms occupies 0.055 moles.

Explanation:

We are given:

Number of silver atoms =

According to mole concept:

1 mole of an element contains number of atoms.

So, using this concept:

As, number of atoms occupies 1 mole of a element.

So, number of atoms will have occupy of silver element.

Thus, the given number of silver atoms occupies 0.055 moles.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

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
