Answer:
There are 1.505×1023 molecules in 0.25 moles of oxygen.
Answer:
Explanation:
Hello,
In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:
So we solve for 
by firstly computing the initial pressure:
Finally, we can compute the work by using the following formula:
Best regards.
I am sure it is DNA polymerase.
