Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable first approximation.)
The vapor pressure of a mixture of 400 g of carbon tetrachloride and 43.3 g of an unknown compound is 137 torr at 30 °C. The vapor pressure of pure carbon tetrachloride at 30 ºC is 143 torr
A solution of 1-pentanol and butanoic acid in ether is shaken with aqueous sodium bicarbonate (NaHCO3) solution. Which of the following correctly describes the major organic contents of the two solutions? Can you explain the answer you chose
