48. GO The diffusion constant for the amino acid glycine in water has a value of 1.06 X 10-º m²/s. In a 2.0-cm-long tube with a cross-sectional area of 1.5 × 10-“ m², the mass rate of diffusion is mlt = 4.2 × 10-1ª kg/s, because the glycine concentration is maintained at a value of 8.3 × 10-³ kg/m³ at one end of the tube and at a lower value at the other end. What is the lower concentration?
A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
