When 0.6 g of element “J” were completely burnt in oxygen and all the heat evolved was used to heat 500 cm3 of water, the temperature of water rose from 230C to 330 C. Calculate the relative atomic mass of element “J” given that the specific heat capacity of water = 4.2J/g/k density of water = 1.0g/cm3 and molar heat of combustion of “J” is 380kj/mole
