Need help on my Chemistry project?
Can someone please help me solve this problem?
If you had one mole of rice grains, how many kilograms of rice would each person on earth have to eat each second of their life?
1 kg = 50,000 rice grains
Approx. population = 7.5 billion
Mole formula = 6.022X10^23
How the heck am I supposed to know how many seconds are in a person's life...
Edit: Apparently the average life expectancy of the world is currently 69.9 years

Then you divide kg of rice by the amount of seconds.[/quote]
Ahh, thanks! I get it now
70 years x (12 months/1 year) x (30 days/1 months) x (24 hours/1 day) x (60 minutes/1 hours) x (60 seconds/1 minute)
Then you divide kg of rice by the amount of seconds.
@crazymaster: It's asking how many kg of rice they have to eat each second, not how long.
It's asking you how long it would take for the people of Earth to finish eating the rice.
You get no second life.
