2. Propane is typically burned to heat the air in a hot air balloon. Prof. Sakimoto has a crazy idea to simply use the propane as the "lifting gas". Using the molar mass of propane (C3H8, 44.097 g/mol), what is the density of propane gas on a cold day (10.0 C, 1.00 atm). Assuming the density of air at the same conditions is 1.25 kg/m, why would Prof. Sakimoto's idea not work? consumption of Ca)? mol/day of X leads to loukemia and bosc sarcomas
