Question

Which is more concentrated a 50ml vinegar with 1 stick of chalk, 50ml vinegar with 2 sticks of chalk or 100ml vinegar with 1 stick of chalk?

Answer 1

Well, I would say `2` sticks of chalk in `50 \ "mL` of vinegar.

Explanation:

I would solve the problem like this.

For this problem, the concentration formula would be:

`"concentration"="sticks of chalk"/"volume of solution"`

Let's measure it with the unit `"C"`, for example.

For the first solution, the concentration would be

`1/50"C"`

For the second solution, the concentration would be

`2/50=1/25"C"`

For the third solution, the concentration would be

`1/100"C"`

We know that

`1/25>1/50>1/100`

and since `"C">0` for all `"C"inRR`

`:.1/25"C">1/50"C">1/100"C"`

`=>` The second solution would be the most concentrated.
