when a 1421 J of heat energy is added to 39.5 g of hexane, C6H14, the temperature increases by 15.9 degree centegrade. Calculate the molar heat capacity of C6H14.
element mercury has a density of 13.6 g/ml. how many kg of mercury could occupy a volume of 500ml?
Suppose that a sample of gas occupies 192 mL of volume at 25C and a pressure of 206 torr. What would be the volume if the pressure were changed to 506 torr at 25C.
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
A 10.4-g sample of CaCl2 is dissolved in 107 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C ..
