A container with 0.221 L of water is placed in a microwave and is then radiated with electromagnetic energy that has a wavelenth of 11.7 cm. The temperature of the water then rose by 65.5 0C. Calculate the number of photons that were absorbed by the water. Assume water has a density of 1.00 g/ ml and its specific heat is 4.184 J/ G 0C
Consider the same dilution above for an SN1 reaction. Would the time required for 95% for the starting material to react change as a result of this dilution?
