Heating 235 g of water from 22.6°C to 94.4°C in a microwave oven requires 7.06 × 104 J of energy. If the microwave frequency is 2.88 × 1010 s−1, how many quanta are required to supply the 7.06 × 104 J? The value for Planck's constant is 6.63 × 10-34 Jᐧs/quantum. The formula to use is Energy / (Planck's constant x Frequency).
