Makes zero sense. What’s the question?
Answer:r=1.2 d=2.4
Explanation:
Radius is half the diameter and the diameter is 2.4 m
Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:
mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
