Density of Carbon tetrachloride = 1.59 g/mL

Mass of Carbon tetrachloride = 55 g

Calculations:

1. Calculate the number of moles of Carbon Tetrachloride present in 55 g:

Moles of Carbon Tetrachloride = Mass / Molar Mass

Moles of Carbon Tetrachloride = 55 g / 153.82 g/mol

Moles of Carbon Tetrachloride = 0.358 mol

2. Since there are 4 Chlorine atoms per molecule of Carbon Tetrachloride, we can calculate the total number of Chlorine atoms:

Total number of Chlorine atoms = 4 * Moles of Carbon Tetrachloride

Total number of Chlorine atoms = 4 * 0.358 mol

Total number of Chlorine atoms = 1.43 mol

3. Convert moles of Chlorine atoms to the number of atoms:

Number of Chlorine atoms = Moles of Chlorine atoms * Avogadro's Number

Number of Chlorine atoms = 1.43 mol * 6.022 x 10^23 atoms/mol

Number of Chlorine atoms = 8.62 x 10^23 atoms

Conclusion:

Therefore, there are approximately 8.62 x 10^23 Chlorine atoms present in 55 g of Carbon Tetrachloride.
