Question

Calculate the number of moles in 18.06×10^23 of the sodium element

Answer 1

We are given:

Number of sodium atoms = 18.066\times 10^{23}

According to mole concept:

1 mole of a compound contains 6.022\times 10^{23} number of molecules.

So, using this concept:

As, 6.022\times 10^[23} number of atoms occupies 1 mole of a element.

So, 18.066\times 10^{23} number of atoms will have occupy \frac{1mole}{6.022\times 10^{23}}\times 18.066\times 10^{23}=3mole of sodium element.

Thus, the given number of sodium atoms occupies 3 moles.
