When scientists obtain the biomass of samples, they heat it at 75 °C for 2 hours. They weigh the sample, reheat it for 15 minutes and weigh it again. They continue this cycle of reheating and weighing until they find the sample has a constant mass. Explain how this method helps to provide a reliable measurement of the biomass. (2 marks)
