A balloon is floating around outside your window. The temperature outside is -19 ∘C , and the air pressure is 0.800 atm . it has 3.00 mol of gas. Whats the volume

Answer 1

PV = nRT ... Ideal Gas Law

P = pressure = 0.800 atm

V = volume in L = ?

n = moles = 3.00 mols

R = gas constant = 0.0821 Latm/Kmol

T = temperature in Kelvin = -19ºC +273 = 254K

Solving for V ...

V = nRT/P = (3.00)(0.0821)(254) / 0.800

V = 78.2 L
