Question

Volume of 2.93 L, what will its pressure? 0.499 am

3. Hospitals buy 400-L cylinders of oxygen gas compressed at 150 atm. They administer oxygen to
patients at 3.0 atm in a hyperbaric oxygen chamber. What volume of oxygen can a cylinder
supply at this pressure?
?

Answer 1

The volume of Oxygen : 20,000 L

Further explanation

Given

400 L : initial volume

150 atm : initial pressure

3 atm : final pressure

Required

Final volume

Solution

Boyle's Law

At a fixed temperature, the gas volume is inversely proportional to the pressure applied

`\rm p_1V_1=p_2.V_2\\\\(p_1)/(p_2)=(V_2)/(V_1)`

Input the value :

V₂ = (P₁V₁)/P₂

V₂ = 150 atm x 400 L / 3 atm

V₂ = 20,000 L
