Quizplus · Accepted Answer

According to the American Heart Association, the average weight of an adult in the United States is about 80 kg. Assuming that the students in the physics class are all adults and have an average weight of 80 kg, the total mass of the 150 students would be:

150 students x 80 kg/student = 12,000 kg

This is closest to choice C, which is 10^14.
