Every year near the end of June, your grandpa picks his strawberries and makes his famous jam. Afterthirty years of making this jam, your grandpa has found that on average the strawberries contain about 15weight percent solids and the rest is pure water. After crushing the strawberries, he mixes them with sugarin a mass ratio of 45:55 at ambient conditions. He places the mixture in a stainless steel boiler andevaporates most of the water, leaving one-third water by mass remaining in the boiler pot. Since yourgrandpa is very proud that you are majoring in chemical engineering, he asks you to answer some questionsabout making strawberry jam. How many pounds of strawberries are needed to make a pound of jam, andwhat are the mass fractions of solids and sugar in that jam? Based on evaporating the water at 1.0 atm, howmuch heat must be added to the boiler pot? When the jam is poured into a glass jar that is 3.0 inches indiameter and 6.0 inches high, what percentage of the height does it fill?

For a metric ton of jam, what amount of strawberries is needed? What is the cost to produce this metricton, based on industrial electricity prices as reported by the U.S. Energy Information Administration?
