With a mole of skittles placed side by side, you can go around the earth <span>191.17 trillion times.
I hope this helps! If it didn't please reply. Please mark it the brainliest if it did!
</span>(6.022x10^23) x .5" = 3.011x10^23 inches.
<span>3.011x10^23 / 12 in per ft(=.251)
</span><span>.251 /5280 ft per mile = 4.75x10^18 miles
</span><span>4.75x10^18 miles / 24850 mile around the earth = 1.9117x10^14 time around the earth.

Structures that were needed for an organism's ancestor, but no longer required for survival for the current organism. We needed our wisdom teeth and appendix in order to eat tougher foods, but now we do not need those to survive. But, we still have them.
D=m/v
m=6914g
v=4.00
Convert Liters to cm...
4l(1000cm^3/1L)=4000cm^3
D=6914g/2000cm^3=1.7285g/cm^3
