<u>Answer:</u> The number of atoms of carbon present in given number of moles are 2.350\times 10^{20}

<u>Explanation:</u>

We are given:

Number of moles of carbon = 3.900\times 10^{-4}mol

According to mole concept:

1 mole of an element contains 6.022\times 10^{23} number of atoms.

So, 3.900\times 10^{-4}mol of carbon will contain = 3.900\times 10^{-4}\times 6.022\times 10^{23}=2.350\times 10^{20} number of atoms.

Hence, the number of atoms of carbon present in given number of moles are 2.350\times 10^{20}
