A chemist has 500ml of a salt solution that contains 2% salt in units of g/cm squared. How much water must be added to reduce the concentration to 0.5%
Its G/ CM CUBED
(49/50)(500ml)(3) should work. The reason is that if 49 parts water out of 50 make 98% water, then that's 2% salt by weight.
so therefore you want to quadruple the water to go from 2 to 1 to 1/2 of a percent salt. So add 3 more times the 49 parts.
Am i right?

Actually, I think 1500ml must be added.

Taking a new step, uttering a new word, is what people fear most. ― Fyodor Dostoyevsky, Crime and Punishment
The knowledge of some things as a function of age is a delta function.
Mrs b agrees with 1500 & with g per cm cubed.
