you are geometrically diluting/mixing 0.1 g of powder A with 100g of powder B, how many times do you have to mix the 2 together to finish the process?

*each time you can only mix an equal portion of powder B to what you currently have mixed.

Eg.

1:1

2:2

4:4

3. The Attempt at a Solution

So the first time you mix them it will be

0.1 g + 0.1 g --> 2^0

then

0.2 g + 0.2 g --> 2^1

Would the correct formula be 101.1 = 0.1*2^n ???

help?? thanks
