A given calorimeter has a heat capacity of 1550 J°C-1. When a certain mass of a metal was burned in the calorimeter that contained 150 g of water an increase in temperature of 1.211 °C was observed. The heat given off by burning the metal is 320 kJ mol-1. The metal forms a carbonate that has 14.23% carbon and 56.93% oxygen. The specific heat of water is 4.184 J g-1°C-1. Find the mass of the metal burned in the calorimeter.
