Answer:
<h2>111 kPa</h2>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new pressure
We have
We have the final answer as
<h3>111 kPa </h3>

average atomic mass of Cu = 63.54
Explanation:
average atomic mass = atomic mass of isotope 1 × abundance of isotope 1 + atomic mass of isotope 2 × abundance of isotope 2 +...+ atomic mass of isotope n × abundance of isotope n
average atomic mass of Cu = atomic mass of Cu-63 × abundance of isotope Cu-63 + atomic mass of isotope Cu-65 × abundance of isotope Cu-65
average atomic mass of Cu = 62.93 × (69.17 / 100) + 64.93 × (30.83 / 100)
average atomic mass of Cu = 63.54
