A 16.0 g sample of quartz, which has a specific heat capacity of 0.730 J·g '.°C ', is dropped into an insulated container containing 250.0 g of water at 30.0 °C and a constant pressure of 1 atm. The initial temperature of the quartz is 90.7 °C. Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water. Be sure your answer has the correct number of significant digits.

When 3.43 g of a certain molecular compound X are dissolved in 90. g of dibenzyl ether ((C,H;CH,),0), the freezing point of the solution is measured to be -3.2 °C. Calculate the molar mass of X. If you need any additional information on dibenzyl ether, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to the correct number of significant digits. olo
