A 155.0 −L helium tank contains pure helium at a pressure of 1835 psi and a temperature of 298 K. How many 3.5−L helium balloons can be filled from the helium in the tank? (Assume an atmospheric pressure of 1.0 atm and a temperature of 298 K.)

5528 balloons

Explanation:

Explanation:

At constant pressure and number of moles, using Boyle's law  

Given ,  

V₁ = 155.0 L  

V₂ = ?

P₁ = 1835 psi

P₂ = 1 atm  = 14.7 psia

Using above equation as:

Volume of each balloon = 3.5 L

Thus, number of balloons,

it means there are 3 atoms of oxygen

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
