Suppose that the microwave radiation has a wavelength of 11.2 cm. How many photons are required to heat 235 mL of coffee from 25.0 ^circ rm C to 62.0 ^circ rm C? Assume that the coffee has the same density, 0.997 g/mL, and specific heat capacity, 4.184 rm J/(gcdot K), as water over this temperature range.Express the number of photons numerically.
