help with scientific notation/measuring problem

Question

duncan knows that it takes 36400 cal of energy to heat a pint of water from room temperature to boiling. However Duncan has prepared ramen noodles so many times that he doesn't need to measure the water carefully. If he happens to heat 0.600 pint of room-temperature water, how many kilosjoules of heat would have been absorbed by the water at the moment it begins to boil

Answer 1

Heat absorbed by the water at the moment it begins to boil = 0.6 * 36400 cal = 0.6 * 36400 * 4.184 / 1000 KJ (as 1 cal = 4.184 Joules) = 91.37856 KJ
