Both enriched uranium fuel and biomass wood pellets can be used as energy resources for generating electricity in power stations.
1 kg of enriched uranium fuel can result in the generation of 7.2×107 MJ7.2 \times 10^7\text{ MJ}7.2×107 MJ of electricity.
1 kg of biomass wood pellets can result in the generation of 1.8×101 MJ1.8 \times 10^1\text{ MJ}1.8×101 MJ of electricity.
Calculate the mass of biomass wood pellets, in tonnes, needed to generate the same amount of electricity as 1.5 kg of enriched uranium fuel. (1 tonne=1000 kg1\text{ tonne} = 1000\text{ kg}1 tonne=1000 kg)
