300 grams of copper metal at 90 degrees celsius is added to a beaker that holds 15.0 grams of ice and 80.0 grams of water at 0.0 celsius. As the copper cools, the ice melts and tehn the 95.0 grams of water warms, reaching a final temperature of 10.0 celsius. Calculate the specific heat of copper metal in joules/ grams x celsius.
