Two gas cylinders are identical. One contains the monatomic gas argon (Ar), and the other contains an equal mass of the monatomi
c gas krypton (Kr). The pressures in the cylinders are the same, but the temperatures are diff erent. Determine the ratio KEKrypton KEArgon of the average kinetic energy of a krypton atom to the average kinetic energy of an argon atom.

Weight of the balloon = 2.0 g
Six weights each of mass 30.0 g is added to the balloon.
Total mass of the balloon = 2.0 g + 6*30.0 g = 182 g
Density of salt water = 1.02 g/mL
Calculating the volume from mass and density:
Converting the volume from mL to cubic cm:
Assuming the balloon to be a sphere,
Volume of the sphere = π
r = 3.49 cm
Radius of the balloon = 3.49 cm
Diameter of the balloon = 2 r = 2*3.49 cm = 6.98cm
