A balloon is partially inflated with 5.00 L of helium at sea level, where the atmospheric pressure is 1.00 atm. The balloon ascends to altitude of 1600 meters and its volume increased to 6.00 L. Assuming that the temp of the gas didnt change during the ascent, calculate the atmospheric pressure at 1600 meters in mmHg.
