A chemical reaction converts a certain chemical into another chemical, and the rate at which the first chemical is converted is proportional to the amount of this chemical present at any time. At the end of two hours, 80 grams of the first chemical remain, while at the end of four hours, only 40 grams remain. How many grams of the first chemical were present initially?
