Thank you for posting your question here at brainly.

E = mc^2
where E is the energy in joules, 
m is the mass in kilograms, 
and c is the speed of light. 

E = mc^2 
E = (5.63 x 10^-7 kg)(3 x 10^8 m/s)^2 
E = 5.07 x 10^10 J

A sample of n2 occupies 3. 0l at 3. 0atm. What volume will it occupy when the pressure is changed to 0. 5atm and the temperature

belka [17]

It will occupy 18 L volume when the pressure is changed to 0. 5 atm and the temperature remain constant.

Calculation,

According to Boyle law, the pressure of a given quantity of gas varies inversely with its volume at constant temperature.

$P_{1} V _{1} = k$ .....(i)

$P_{1}$ is initial pressure = 3 atm
$V _{1}$ is initial volume = 3L
k is constant

$P_{2} V _{2} = k$ (ii)

$P_{2}$ is final pressure = ?
$V _{2}$ is final volume = 0.5atm
k is constant

Combining equation (i) and (ii). we get,

$P_{1} V _{1} = P_{2} V _{2}$

3 atm× 3L= $V _{2}$ × 0.5atm

$V _{2}$ = 3 atm× 3L/0.5atm = 18 L

Boyle law used during respiration or breathing.
