One M&M candy has a volume of 1.0mL. What volume, in cubic meters, would one mole of M&M candies occupy?

2) For this next calculation, you’re going to compare the volume of a mole of M&Ms to Lake Erie, which has a volume of 116mi^3. How many lakes the size of Lake Erie would a mole of M&M candies fill?

3) A package of 50 M&M candies costs 50 cents. How much would a mole of M&Ms cost, in dollars? Given that the annual budget of the United States is approximately two trillion dollars ($2 X 10^12), how many years would it take for the US to pay for a mole of M&Ms?

I will do the first one for you to get you started.
1 M&M = 1.0 mL; therefore, 1 mole of M^Ms will be 6.022 x 10^23 mL = 6.022 x 10^23 cc. Tjere are 1 x 10^6 cc in 1 m^3.
6.022 x 10^23 cc x (1 m^3/1 x 10^6 cc) = ?? m^3.
