Solution in ppm="when 1mg compound dissolved to 1000ml it
is 1ppm solution".1% solution means 1gm dissolved to 100ml
so
1gm is nothing but 1000mg, 1000mg dissolved to 1000 ml
gives 1000ppm and as this 1gm dissolved to 100ml this is
100000 ppm solution.

Answer / srinivas

1 gm in 100 ml is 1% Solution

1 gm = 1000 mg

1 mg = 1000 ppm

1% Solution = 1000000 ppm
