A chemist mixes one liter of pure water with x liters of a 45% salt solution, and the resulting mixture is a 15% salt solution. What is the value of x? Choose the correct choice from the following choices: A) 1/4 B) 1/3 C) 1/2 D) 1 E) 3
1/2oncentration of salt in pure solution = 0   1/2oncentration of salt in salt solution = 45%   1/2oncentration of salt in the mixed solution = 15%   The pure solution and the salt solution is mixed in the ratio of --&gt; (45 - 15)/(15 - 0) = 2/1   1/x --  (45 - 15)/(15 - 0)=
