Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity
Use PV =nRT. Rearrange it to n = PV/RT. P = 202.6 kPa V = 4.0L R = 8.314 kPa*L/mol*K T = 127 °C + 273 = 400 K Plug it in and solve. I got 0.24 moles of H2.
