(11/15) Quiz: Heat Calculations (L) POSSIBLE POINTS 19.44
A student must use 225 g of hot water in a lab procedure. Calculate the amount of heat required to raise the temperature of 225 g of water
from 20.0°C to 100.0°C. The specific heat of water is 4.18 J/gºC.
Answer
Is this process Endothermic or Exothermic?

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
