Answer to Question #77903 in General Chemistry for Chloe Lozano

Question

A balloon contains 46.3 L of Helium at 42 oC, and 2.01 atm is released into the air. At a certain altitude, the temperature falls to 21 oC, and the pressure falls to 0.25 atm. What is the volume of the balloon under these conditions?

A. 3.5 L
B. 35.0 L
C. 347.5 L
D. 3475.0 L
E. None of the Above

Answer 1

Solution
P1V1/T1 =P2V2/T2
2.01•46.3/(42+273.15) =0.25•V2/(21+273.15)
V2=347.5 L
Answer: C. 347.5 L
