Some water dissolves in liquid methane at 2161°c to give a solution in which the mole fraction of water is 6.0 × 1025. determine the mass of water dissolved in 1.00 l of this solution if the density of the solution is 0.78 g cm23.

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
