Compare the mass of an ice cube to the mass of the water once the cube is completely melted.
a) the mass of water formed equals the mass of ice.
b) the mass of water formed is more than the mass of ice.
c) the mass of water formed is less than the mass of ice.
d) the mass of water formed does not depend on the mass of ice.

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
