What is the molar mass of X if 0.85g of X depresses the freezing point of 100g of benzene by 0.47Cdegrees?
Calculate Delta G and Delta A for the vaporization of 1.00 mol H2O at 1.00 atm and 100 ?C. Consider the process reversible. The density of H2O(l) at 100 ?C and 1 atm is 0.958 g/cm3.
If an archaeologist finds an ancient firepit containing partially consumed firewood, and the 14C content of the wood is only 13.1% that of an equal carbon sample from a present-day tree, what is the age of the ancient site?
