A spacecraft is fueled using hydrazine (N,H, molecular weight of 32 grams per mole [g/moll) and carries 1,634 kilograms [kg] of fuel. On a mission to orbit a planet, the fuel will first be warmed from - 199 degrees Fahrenheit [F] to 91 degrees Fahrenheit (°F] before being used after the long space flight to reach the planet. The specific heat capacity of hydrazine is 0.099 kilojoules per mole kelvin (kJ/mol K)]. If there is 400 watts [W] of power available to heat the fuel, how long will the heating process take in units of hours [h]?
