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?]]>http://www.mathisfunforum.com/profile.php?id=11082013-02-21T02:15:59Zhttp://www.mathisfunforum.com/viewtopic.php?pid=254463#p254463Its G/ CM CUBED]]>2013-02-18T10:29:25Zhttp://www.mathisfunforum.com/viewtopic.php?pid=254216#p254216A chemist has 500ml of a salt solution that contains 2% salt in units of g/cm squared.
