A rubber balloon with a mass of 179 grams is inflated to a diameter of 95 cm with helium gas. The air temperature is 32ºC and the air pressure is 769 mmHg. Assume the helium has a gauge pressure of 68 mmH and the same temperature as the air. Find the net force acting on the balloon (treat up as positive and down as negative). Air has a molar mass of 29.0 g/mol (amu), and helium 4.00 g/mol. Round to the nearest 0.01 newton.
