    A hot air balloon starts to take off when the temperature inside the balloon is 111 °C higher than the outside air. The pressure is the same inside and outside the balloon and there is a total of 2.50× 105 moles of air in the balloon. Assuming that the air density outside of the balloon is 1.20 kg/m3, what is the total mass of the balloon and its load? The answer is 2.73 × 103 kg. I am not sure...

    2 attempts left Check my work Be sure to answer all parts. A biochemical engineer isolates a bacterial gene fragment and dissolves a 16.0-mg sample in enough water to make 30.0 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C. (a) What is the molar mass of the gene fragment? g/mol (b) If the solution density is 0.997 g/mL, how large is the freezing point depression for this solution (K of water = 1.86°C/m)?

    The air in a hot-air balloon is heated to make the balloon rise. The air in a hot-air balloon is heated to make the balloon rise. The size of gas molecules increases with temperature. The pressure inside the balloon decreases and the balloon rises to equilibrate with the atmospheric pressure. The attractive forces between the particles of the gas inside the can become stronger. The particles spread farther apart and the density of air in the balloon becomes less than...

    We consider a hot-air balloon of mass 231 kg (basket and envelope). The spherical envelope of the balloon has a diameter of 15 m when fully inflated. To what temperature (in °C) must the enclosed air be heated for the balloon to carry five standard men? Assume the surrounding air is at 20°C and is treated as an ideal gas. Use 29 g/mol for the molar mass of air. (Assume the mass of each standard man is 70 kg.)
