Aspacecraft is fueled using hydrazine (n2h4; molecular weight of 32 grams per mole [g/mol]) and carries 1640 kilograms [kg] of fuel. on a mission to orbit a planet, the fuel will first be warmed from −186 degrees fahrenheit [°f] to 78 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 300 watts [w] of power available to heat the fuel, how long will the heating process take in units of hours [h]?
