Step 1
To find the number of atoms in any quantity of moles you just need to multiply the number of, moles times Avogadro's constant.
Which will gives the number of molecules, and then multiply by the number of atoms is one molecule which is
$5 (C, H, and 3 C l)$ .
The calculus is $1.75 m o l \times 6.02 \times 10^{23}$ $\frac{m o l e c u l e s}{m o l} \times 5 \frac{a t o m s}{m o l e c u l e}$
$= 52.675 \times 10^{23} a \to m s$
$= 5.2675 \times 10^{24}$ atoms.

1 mol=6.022×1023 (atoms or molecules) 1.75 moles of (CHCl3) we have: 1.75moles×(6.022×1023molecules)=1.05385×1025 molecules. a molecule of CHCl3 have, 1 atom of C, 1 atom of H, and 3 atoms of Cl, therefore a molecule of CHCl3 have 1atom+1 atom+3 atom=5 atoms. Therefore: 1 molecule (CHCl3)⋯5 atoms1.058385×1023 molecules   (CHCl3)⋯xx=1.058385×1024 molecules×5 atoms1molecule≈5.26925×1024 atoms Solution: =5.269×1024 atoms.

To determine the number of atoms in 1.75 mol of CHCl

_{3}

, we need to first calculate the total number of molecules in 1.75 mol of CHCl

_{3}

, and then multiply that by the number of atoms in each molecule.
The molecular formula of CHCl

_{3}

indicates that it contains 1 carbon atom, 1 hydrogen atom, and 3 chlorine atoms.
Avogadro's number,

N_{A}

, is the number of particles in one mole of a substance, and is equal to

6.022 \times 10^{23}

particles/mol.
Therefore, the number of CHCl

_{3}

molecules in 1.75 mol is:

1.75 mol \times 6.022 \times 10^{23} molecules/mol = 1.057 \times 10^{24} molecules

Since each CHCl

_{3}

molecule contains 1 carbon atom, 1 hydrogen atom, and 3 chlorine atoms, the total number of atoms in 1.057

\times

10

^{24}

molecules of CHCl

_{3}

is:

(1 carbon atom/molecule + 1 hydrogen atom/molecule + 3 chlorine atoms/molecule) \times 1.057 \times 10^{24} molecules

= 5.285 \times 10^{24} atoms

Therefore, there are

5.285 \times 10^{24}

atoms in 1.75 mol of CHCl

_{3}

.

The molar mass of CHCl3 can be calculated by adding the atomic masses of its constituent atoms:1×C=12.01 g/mol1×H=1.01 g/mol3×Cl=3×35.45 g/molAdding these values together gives a molar mass of:12.01 g/mol +1.01 g/mol +3×35.45 g/mol =119.38 g/molThis means that 1 mole of CHCl3 has a mass of 119.38 g.Since we have 1.75 moles of CHCl3, we can find the mass of this quantity:1.75 mol ×119.38 g/mol =208.76 gNow, we can use Avogadro&#039;s number to determine the number of atoms in 1.75 mol of CHCl3:1.75 mol ×6.022×1023 atoms/mol =1.057×1024 atomsTherefore, there are 1.057×1024 atoms in 1.75 mol of CHCl3.
