Answer:

950 balloons

Explanation:

P1 = pressure inside cylinder = 20atm

P2 = pressure outside = 640mmhg = 0.842105 atm

V1= volume of cylinder =20L = 20,000 ml

V2 = volume of a single balloon= 500ml

n = number of balloons

[tex]P_{1}V_{1} =n P_{2}V_{2}\\20* 20000 =n 0.842105 * 500\\n = 950.[/tex]
