For this chemistry project, i need to figure out how many holes the size of Lake Michigan a mole of M&Ms would fill. Have the volume of an M&M as 1cm^3 and the vol. of l. michigan as 4918 km^3, which i've converted to centimeters to make easier. im a little stuck now with the FLM setup. im not asking anyone to try to do the problem, just to help me set it up correctly. Thanks!

Well,
1km = 1000m
1 m = 100 cm
so 1km = 1km*(1000m/km)*(100cm/m) = 10^5cm
and km^3 = (10^5cm)3 = 10^15cm^3
is that enough to get you started??

Volume 1 mole of M&M's:
6.02E23 cm^3 = 6.02E8 km^3
Number of moles to fill Lake Michigan:
4918/6.02E8 = 8.17E-6 moles
1 mole will fill 122,000 lakes.
