10,000 ppm

Solution Method:

1. A ppm = 1/1,000,000 = 0.000001

2. What you want to know is: how many ppm would = 1%

3. p * .000001 = .01

4. p = .01 / .000001

5. p = 10,000

You could also do it this way:

1. 1% of 1,000,000 = ppm = 10,000 ppm (but that method lacks a clear path to understanding).

===

previous answer's method:

1%=1/100=1000000/100=10000ppm.
