3.2 Dissipation and efficiency

Question 8

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 $7.2 \times 10^7\text{ MJ}$ of electricity.

1 kg of biomass wood pellets can result in the generation of $1.8 \times 10^1\text{ MJ}$ 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. ( $kg1\text{ tonne} = 1000\text{ kg}$ )
