How many moles are there in 5.2x10^23 atoms of CO2?

0.86 moles of CO₂

Explanation:

Given data:

Number of atoms of CO₂ = 5.2×10²³ atom

Number of moles = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

5.2×10²³ atom× 1 mol / 6.022 × 10²³ atoms

0.86 mol

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
