An arctic weather balloon is filled with 6.15 L of helium gas inside a prep shed. The temperature inside the shed is \( 9 .{ }^{\circ} \mathrm{C} \). The balloon is then taken outside, where the temperature is \( -28 .{ }^{\circ} \mathrm{C} \). Calculate the new volume of the balloon.
You may assume the pressure on the balloon stays constant at exactly 1 atm. Round your answer to 3 significant digits.
5.34 L
\( \square \times 10^{\square} \)
