Answer:

6.286 L.

Explanation:

Applying Charles Law,

V/T = V'/T'............................... Equation 1

Where V = Initial volume of the balloon, T = Initial Temperature of the balloon, V' = Final volume of the balloon, T' = Final Temperature of the balloon

make V' the subject of the equation

V' = VT'/T............................ Equation 2

Given: V = 6.50 L, T = 31 °C = (273+31) K = 304 K, T' = 21 °C = (273+21) K = 294 K

Substitute into equation 2

V' = 6.5(294)/304

V' = 6.286 L.

Hence the new volume in the balloon = 6.286 L.
