**1.**Asume that you distribute Avogadro's Number of dollars evenly among each of the

**4.5 x 10**people on earth. Further, assume that everyone spends $1000 each second, day and night.

^{9}What percentage of each person's wealth will have been spent after one year?

**2.**Avogadro's Number =

**6.02 x 10**

^{23}**3.**a)

**"distribute evenly among"**=

**(6.02 x 10**

^{23}/ 4.5 x 10^{9})because $/ppl

b)

**"everyone spends $1000 each second... after one year"**=

**($1000 x 3.1536 x 10**

^{7}s) = 3.1536 x 10^{10}(31536000 = 60 s x 60 min x 24 hr x 365 day)

c)

**"What percentage of**

*each*person's wealth will have been spent after 1 year"each person's total wealth = x

percent spent = n

$/year = 3.1536 x 10

^{10}

percent spent / each person's total wealth = total spent / amount distributed

percent spent / each person's total wealth = total spent / amount distributed

**n / x =**(

**3.1536 x 10**) / (

^{10}s**6.02 x 10**)

^{23}/ 4.5 x 10^{9}cross multiplying leaves me with:

**(6.02 x 10**

^{23})n = (3.1536 x 10^{10}x 4.5 x 10^{9})x----

This is an exercise in my chem book, trying to get us to appreciate the scale of Avogadro's Number.. so it isn't answered. But, is this the correct way to think a problem like this through?
