Calculate the number of years it would take for 7 billion people to count one mole of pennies at the rate of one penny per second
that's awful... ohhh dimensional analysis..
Btw ...mole is 6.022 x 10^23
ok, remind me units for a mole. is it grams or does it have units at all?
cuz it's Avagrado's number
you don't need units for this question
I did other questions similar to this .but for some reason I'm just not getting this one....
trying to figure out a way...
i need units for a mole please. I can't remember chem was a looong time ago, and that affects the math
Avagrado's number has the units of MOL......mol is a UNIT in chemistry
ok, so it's just a number, not in grams or anything. That would make this harder. Ok, so. How many pennies are counted per second?
by the 7 million people
billion*
one mole of pennies..so 6.022 x 10^23
no, re read how many pennies each person counts per second
