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>Hope this helps you
Answer:
The fraction of the volume of the atom that is taken up by the nucleus is .
The density of a proton is .
Explanation:
Diameter of the atom ,d = 2.50 Å
Radius of the atom ,r = 0.5 d=0.5 × 2.50 Å = 1.25Å
Volume of the sphere=
Volume of atom = V
..[1]
Diameter of the nucleus ,d' =
Radius of the nucleus ,r' = 0.5 d'=
Volume of nucleus = V'
..[2]
Dividing [2] by [1]
The fraction of the volume of the atom that is taken up by the nucleus is .
Diameter of the proton ,d =
1 m = 100 cm
Radius of the proton,r = 0.5 d=
Volume of the sphere=
Volume of atom = V
Mass of proton, m = 1.0073 amu =
Density of the proton : d
The density of a proton is .
