Assuming the validity of raoult’s law, do the following calculations for the benzene (1)/toluene(2) system:

(a). given x1=0.33 and t=100oc , find y1and p
(b). given y1=0.33 and t=100oc , find x1and p
(c). given t=105oc and p=120kpa , find x1and y1
(d). for part c), if the overall mole fraction of benzene is z1=0.33, what molar fraction of the two-phase system is vapor?

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
