Chemistry problem dealing with moles..help!?
Convert km to inches and multiply time the length of the mole ( mammal ) by 6.022 X 10^23. Then do some ratio comparison; divide.
Reply:11.8x10^9 km x 1000 m/km x 100 cm/m x (1 in/2.54 cm)(1 mammal/ 7 in)x (1 mole/6.022x10^23 mammals) = 1.10x10^-10 moles of mammals
