I am assuming that the temperature given is in Celsius. In order to solve for the heat capacity, use q = mc△T. Your q = -5890.0J, m = 50.0 g, and △T 33.0 °C (69.0 - 36.0). Use algebra to solve for your heat capacity (c). Remember, heat capacity is measured in joules per gram Celsius (J/g °C), and don’t forget your significant figures.
