A 81 kg injured astronaut is sitting in a modern version of dumb waiter (a hand operated elevator 19 kg system) that is being pulled up with a force of 200.0 N. Fortunately, this elevator ride is taking place on the moon and actually accelerates. How long will it take the injured astronaut and elevator system to move from the lunar surface 2.5 m up into the lunar landing module? The moon has a mass of 7.36 x 1022 kg and a radius of 1 738 km.
Stearic acid has a freezing point of 71.20 C and a Kf of 4.890C/m. A 400.0 g quantity of stearic acid to which 50.0 g of an unknown is added has a freezing point of 68.00C. Calculate the molar mass of the unknown.
