!!!!help Me Please  Word Problem Chemistry Related!!!!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% #3 20130221 13:15:59
Re: !!!!help Me Please  Word Problem Chemistry Related!!!!(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. igloo myrtilles fourmis #4 20130221 18:17:02
Re: !!!!help Me Please  Word Problem Chemistry Related!!!!Actually, I think 1500ml must be added.
