Hi, can anyone please help me with this question?
A 2g sample of biomass was fully combusted in a calorimeter. The volume of water in the calorimeter was 100 cm*3. The increase in temperature recorded was 15.7 °C
4.18 J of energy are needed to increase the temperature of 1cm*3 of water by 1°C
Use this information to calculate the heat energy released in KJ per g of biomass. Show your working. (3 marks)
