Answer: 5 All of the molecules have the same kinetic energy
since the temperature is kept constant at 298 K
Explanation:
The AVERAGE kinetic energy is directly proportional to the absolute temperature.
It indicates that there is only one oxygen molecule
Moles are the product of the molar concentration and the volume of the solution. The moles of Ferric chloride is 0.118 moles.
<h3>What are moles?</h3>
Moles are the smallest unit of the measurement of atoms and molecules. It is calculated by the molar concentration and the volume of the solution.
Given,
Molar concentration of ferric chloride = 0.762 M
Volume of solution = 0.155 L
Moles are calculated as:
Therefore, 0.118 moles of ferric chloride are present in the sample.
