Answer:
2.408x10^24 molecules
Explanation:
1mole of a substance contains 6.02x10^23 molecules.
This means that 1mole of C3H8 contains 6.02x10^23 molecules.
Therefore, 4moles of C3H8 will contain = 4 x 6.02x10^23 = 2.408x10^24 molecules
The statement is true. The relationship between the kinetic energy of molecules and the temperature of these molecules are in direct proportionality. Therefore, the temperature generally increases as average kinetic energy also increases. We can relate the two qualities using the Boltzmann equation.
