340 mL of 95 hot water is put into an insulated 140 g copper container at 25 . How many grams of ice at 0 must put into the container to reach a final temperature of 15 for all the substances inside and including the container? (c_ice = 2090 J/kg; c_water = 4186 J/kg; c_copper = 387 J/kg; L_f = 3.33 x 10⁵ J/kg; L_v26 x 10⁶ J/kg)
