Word Problems with conversion factors (Show your work for credit). a. A sample contains 2472 atoms of phosphorus atoms. If each atom of phosphorus has 15 protons, what is the total number of protons in the sample? b. A bicycle factory is assembling bicycles. In order to make 2200 bicycles this month, how many cases of pedals will be needed? (Each case of pedals contains 12 pedals. Each bicycle needs two pedals.) c. The distance from the earth to the moon is 2.4 x 105 mi. Light (and radiowaves) travel at 3.0 x 1010 cm/sec. How long does it take for a radio signal to reach the moon? 6. According to Charles' Law, the volume of a given sample of a gas at constant pressure, is directly proportional to absolute temperature. The following data was obtained on a sample of gas.
