Question

A grocery store has 75 dozen packages of hotdogs In stock. If there are 10 hot dogs in each package, how many moles of hot dogs is this?

Answer 1

you can just divide 75 and 10

Answer 2

`1.49*10^(-20)hotdogmoles`

Step-by-step explanation:

First we will calculate the amount of hot dog units we have:

-75 dozen packages (a dozen is 12 )=75x12=900 packages

-each package has 10 hot dogs=900x10=9000 hot dog units

We know a mole of something is
`6.022*10^(23)` units of that something. And that will be our conversion factor for this excercise. We will convert now from 9000 units of hot dogs to moles of hot dogs like this:
`9000 hotdogunits*(1 hotdogmoles )/(6.022*10^(23)hotdogunits )=1.49*10^(-20)hotdogmoles`
