At a local conveience stor, you purchase a cup of coffee, but at 98 degree celsius, it is too hot to drink. you add 23.0 g of ice that is -2.2 degree celsius to 248 ml of the coffee. what is the final temperature( in degree celsius) of the coffee? ( assume the heat capacity and density of the coffee are the same as water and the coffee cup is well insulated)
change of heat of fuss=6.01 KJ/mol, change of heat of vap=40.67 KJ/mol, C water=37.1/mol. 0c, speciffic heat capacity of water(l)=75.3J/mol.0c and specific heat capacity of water(g)=33.6J/mol.oc
