Explain the number of photons numerically

Reference no: EM13520176

Suppose that the microwave radiation has a wavelength of 12.4 cm. How many photons are required to heat 275 mL of coffee from 25.0 C to 62.0 C? Assume that the coffee has the same density, 0.997 g/mL, and specific heat capacity, 4.184 J/(g K), as water over this temperature range. Express the number of photons numerically.
