Question
i'm doing a project on: one mole of crayons would make ?? number of trips to the sun and back.

crayon in inches=6 inches
earth to the sun=589,480,000,000 inches

mole→ 6.022*10^23

Answer
What exactly to you need help with? If a crayon is 6" long and a mole is 6.022*10^23 then a mole of crays is 6*6.022*10^23=36.132*10^23 inches. So just divide this number by the inches from earth to sun.

36.132*10^23/589480000000=6.13*10^14

trips to the sun. For trips to the sun and back just divide by 2.
