A12.0 g sample of a metal is heated to 90.0 ◦c. it is then dropped into 25.0 g of water. the temperature of the water rises from 22.5 to 25.0 ◦c. the specific heat of water is 4.18 jg−1◦c −1 . calculated the specific heat of the metal. express your answer in jg−1◦c
i know that the answer is 0.335. my question: should there be 2 sig figs (0.34) because 25-22.5=2.5? or is it three sig figs 0.335 because all the original values have 3 sig figs in the beginning.
