Explanation / Answer

Given,

initial balloon conditions

V = 110 L

P = 755 torr/760 = 0.993 atm

T = 20 oC + 273 = 293 K

R = gas constant

So,

moles (n) of He in balloon = PV/RT

                                          = 0.993 x 110/0.08206 x 293

                                          = 4.543 mol

after ascending to an altitude

P = 28 torr/760 = 0.037 atm

T = -38 oC + 273 = 235 K

The volume at which balloon bursts (V) = nRT/P

                                                               = 4.543 x 0.08206 x 235/0.036

                                                               = 2433.55 L
