Problem- A 32.1g iron rod, initially at 22.5C, is submerged into an unknown mass of water at 62.7C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 58.6C. What is the mass of water?
Find the mass of urea (CH4N2O) needed to prepare a 50.2g of a solution in water in which the mole fraction is 7.51*10^-2.
Molecule size: The larger the electron cloud around the molecule, the greater the dispersion forces. The length of the carbon chain among similarly branched hydrocarbons can be used to assess this factor.
