Hi

Mrs b agrees with 1500 & with g per cm cubed.

Actually, I think 1500ml must be added.

(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?

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%
