How many moles of chlorine atoms are present in 4.8x10^20 molecules of carbon tetrachloride?
How many mols CCl4 do you have? That's mols = #molecules/6.02E23 = ?
Then there are 4 atoms Cl for each molecule CCl4; therefore, there are 4 x that number atoms Chlorine
To determine the number of moles of chlorine atoms in 4.8x10^20 molecules of carbon tetrachloride, you need to know the chemical formula of carbon tetrachloride (CCl4).
Carbon tetrachloride consists of one carbon atom (C) and four chlorine atoms (Cl). Therefore, for each molecule of carbon tetrachloride, there are four chlorine atoms.
To find the number of moles of chlorine atoms, you can use the Avogadro's number (6.022x10^23), which represents the number of entities (atoms, molecules, or formula units) in 1 mole of a substance.
Here's how you can calculate it:
1. Determine the number of moles of carbon tetrachloride molecules:
Since you have 4.8x10^20 molecules of carbon tetrachloride, divide this number by Avogadro's number:
4.8x10^20 / 6.022x10^23 = 0.00798 moles of carbon tetrachloride
2. Multiply the number of moles of carbon tetrachloride by the number of chlorine atoms in one molecule:
0.00798 moles of CCl4 x 4 chlorine atoms = 0.0319 moles of chlorine atoms
Therefore, there are approximately 0.0319 moles of chlorine atoms present in 4.8x10^20 molecules of carbon tetrachloride.
