Each person would eat 1 pizza/s*365 day/yr*24h/day*3600s/h = 3.154*10^7 pizzas/year. All the people in the world would eat 5*10^9 times that number, or 1.6*10^17 pizza/yr
Divide 6.02*10^23 pizzas by 1.6*10^17 pizza/year to get get the number of years. It's about 4 million years.
if every single person on this planet (about 5x10^9) could eat 1 pizza every second, how many years would it take them to eat 1 mole of pizza.
1 mole= 6.02x10^23
