The vapor-pressure lowering upon forming solution can be utilized for determining molecular weight of nonvolatile solutes. Consider a solvent with known P1* and molar mass M1. Upon adding m2 kg of a solute tom1 kg of the solvent, the solution vapor pressure has been measured as P.(a) Obtain M2 in terms of the specified values the answer should contain only P1*, P,M1, m1,2, presuming an ideal solution.
How many liters of chlorine gas, measured at STP, would be produced by the electrolysis of molten sodium chloride using a current
Restricting yourself to straight-chain (unbranched) compounds, draw the structures of the possible constitutional isomers of pentene. There are two "variables" -- the position of the double bond; and cis/trans isomerization at that double bond.
