Answer:
The kinetic energy of a molecule of carbon tetrachloride is 8.29 zJ.
Explanation:
The kinetic energy of a molecule of carbon tetrachloride is given by:
Where:
m: is the mass
v: is the speed = 255 m/s
To find the mass we need to find the molar mass for CCl₄, and use the Avogadro's number, knowing that in 1 mol of carbon tetrachloride we have 6.022x10²³ molecules:
A (C) = 12.011 g/mol
A (Cl) = 35.45 g/mol
The molar mass (M) of CCl₄ is:
Now, the mass of 1 molecule of CCl₄ is:
Finally, the kinetic energy of a molecule of carbon tetrachloride is:
Therefore, the kinetic energy of a molecule of carbon tetrachloride is 8.29 zeptoJoule.
