A certain microwave delivers 750. watts (J/s) of power to a coffee cup containing 50.0 g of H2O at 25 degrees C. if the wavelength of microwave in oven is 9,75 cm how long does it take and how many photons must be absorbed to make H2O boil?

specific heat capacity for H2O is 4.18 J degrees C-1g-1. Assume only water absorbs energy of microwaves.
