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.
.....(i)
is initial pressure = 3 atm
is initial volume = 3L- k is constant
(ii)
is final pressure = ?
is final volume = 0.5atm- k is constant
Combining equation (i) and (ii). we get,
3 atm× 3L= × 0.5atm
= 3 atm× 3L/0.5atm = 18 L
Boyle law used during respiration or breathing.

Answer: Molar heat of solution for the salt is 2563 kJ/mol
Explanation:
Let the heat absorbed during reaction be q.
q = Heat gained by solution = ?
m = Mass of water + mass of salt = 100.000 g + 5.556 g = 105.556 g
c = Heat capacity of solution = Heat capacity of water = 4.184 J/g°C
Change in temperature = ΔT = (80.000°C-11.517°C) = 68.483°C
0.01180 moles of salt absorbs = 30245.3 J
1 mole of salt absorbs =
of heat
Thus molar heat of solution for the salt in kJ/mol is 2563
