Answer is: total pressure of the system is 2.4 atm.
Boyle's Law (the pressure volume law): volume of a given amount of gas held varies inversely with the applied pressure when the temperature and mass are constant.
p₁V₁ = p₂V₂ (the product of the initial volume and pressure is equal to the product of the volume and pressure after a change).
1.2 atm · 2 L = p₂ · 1 L.
p₂ = 1.2 atm · 2 L / 1 L.
p₂ = 2.4 atm.
When pressure goes up, volume goes down.
When volume goes up, pressure goes down.
B. The study of matter and energy.
Because physical science is everything that doesn't include organic things.
2 moles
Explanation:
Given parameters:
Mass of Sb = 243.52g
Unknown:
Number of moles = ?
Solution:
The number of moles of any substance can be calculated using the expression below:
Number of moles = 
Molar mass of Sb = 121.76g/mol
Now input the parameters:
Number of moles = 
= 2 moles
