A wad of steel wool (specific heat=0.45J/gC) at 25C is misplaced in a microwave oven, which later is accidentally turned on high. The oven generates microwaves of 13.5 cm wavelength at the rate of 925 moles of those photons per second. All of the photons are converted to high-heat energy, raising the temperature of the steel wool. Steel wool reacts explosively with the oxygen in the oven when the steel wool reaches 400.0C. If the steel wool explodes after 1.55 seconds, how many grams of steel wool were accidentally put into the oven?
