The relative atomic mass of an element is: a. the mass of only the neutrons in the atom's nucleus. b. the mass of its atoms compared to the mass of a carbon-12 atom. c. the mass of its isotopes compared to the mass of a normal atom. d. the mass of its atoms averaged over time.

What happens when the temperature of a solution increases?

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
