Calculate the number of molecules in 12.7 moles carbon dioxide

Hey there!

There are 6.022 x 10²³ molecules in a mole of CO₂.

We have 12.7 moles of CO₂, so let's multiply 6.022 x 10²³ by 12.7.

12.7 x 6.022 x 10²³

75.6 x 10²³

7.56 x 10²⁴

There are 7.56 x 10²⁴ molecules in 12.7 moles of CO₂.

Hope this helps!

for points guys

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
