Two chemicals A and B are combined to form a chemical C. The rate, or velocity, of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially, there are 40 grams of A and 50 grams of B, and for each gram of B, 2 grams of A is used. It is observed that 20 grams of C is formed in 8 minutes. How much (in grams) is formed in 16 minutes? (Round your answer to one decimal place.) 31.98 x gramsTwo chemicals A and B are combined to form a chemical C.
