Step 1 
1 mol=6.022×1023 atoms 
To determine the number of atoms, dimly multiply the number of moles by 6.022×1023 or Avogadros

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 Cl).
The calculus is 1.75mol×6.02×1023 moleculesmol×5atomsmolecule
=52.675×1023 ams
=5.2675×1024 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 atoms1molecule5.26925×1024 atoms
Solution: =5.269×1024 atoms.

To determine the number of atoms in 1.75 mol of CHCl3, we need to first calculate the total number of molecules in 1.75 mol of CHCl3, and then multiply that by the number of atoms in each molecule.
The molecular formula of CHCl3 indicates that it contains 1 carbon atom, 1 hydrogen atom, and 3 chlorine atoms.
Avogadro's number, NA, is the number of particles in one mole of a substance, and is equal to 6.022×1023 particles/mol.
Therefore, the number of CHCl3 molecules in 1.75 mol is:
1.75 mol×6.022×1023 molecules/mol=1.057×1024 molecules
Since each CHCl3 molecule contains 1 carbon atom, 1 hydrogen atom, and 3 chlorine atoms, the total number of atoms in 1.057 × 1024 molecules of CHCl3 is:
(1 carbon atom/molecule+1 hydrogen atom/molecule+3 chlorine atoms/molecule)×1.057×1024 molecules
=5.285×1024 atoms
Therefore, there are 5.285×1024 atoms in 1.75 mol of CHCl3.

The molar mass of CHCl3 can be calculated by adding the atomic masses of its constituent atoms:
1×C=12.01 g/mol
1×H=1.01 g/mol
3×Cl=3×35.45 g/mol
Adding these values together gives a molar mass of:
12.01 g/mol +1.01 g/mol +3×35.45 g/mol =119.38 g/mol
This 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 g
Now, we can use Avogadro'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 atoms
Therefore, there are 1.057×1024 atoms in 1.75 mol of CHCl3.
