SUMMARY
The experiment calculates the density of air using a balloon filled with 0.78 liters of air, which is weighed before and after being submerged in liquid nitrogen. The mass of the balloon's contents is determined to be 1.01 grams, leading to a calculated density of 1.29 kg/m³ using the formula density = mass/volume. The method effectively utilizes buoyancy principles to measure the density of air by assessing the weight difference caused by the displaced air volume when the balloon returns to its original size.
