Review Constants i Periodic Table Part A Three 1.0-L flasks, maintained at 308 K are connected to each other with stopcocks. Initially the stopcocks are closed. One of the flasks contains 1.5 atm of N, the second 5.0 g of H, O, and the third, 0.30 g of ethanol, C,H,O. The vapor pressure of H20 at 308 K is 42 mmHg and that of ethanol is 102 mmHg. The stopcocks are then opened and the contents mix freely What is the pressure? Express your answer to two significant figures and include the appropriate units. ? HA Pretul Value Units Submit Request
