Explanation:
The given data is as follows.
Moles of propylene = 100 moles, = 100 J/mol K
= 300 K, = 800 K
= 2 , = 0.02
Therefore, the assumptions will be as follows.
- The given system is very well insulated.
- The work is done on the system because the given process is a compression process.
- Assume that there is no friction so, work done on the system is equal to the heat energy liberated.
= W
Putting the given values into the above formula as follows.
= W
W =
= J
= 5 MJ
Hence, this shows that a minimum of 5 MJ work needs to be done.
Since, work is very less. Hence, it will not compress the given system to 800 K and 0.02 .

Answer:
15 g/mol
Explanation:
If you need to round 14.8232 g/mol down to 2 significant figures, you start on the left, count in two (14) and round with the next number (.8).
Because 8 is higher than 4, you round up, getting the answer 15.
