A chemist mixes one liter of pure water with x liters of a 60% salt solution, and the resulting mixture is a 15% salt solution. What is the value of x?
Answer/Solution
1/3
Steps/Work
Concentration of salt in pure solution = 0
Concentration of salt in salt solution = 60%
Concentration of salt in the mixed solution = 15%
The pure solution and the salt solution is mixed in the ratio of --> (60 - 15)/(15 - 0) = 3/1
1/x = 3/1
x = 1/3
Answer: B
Concentration of salt in salt solution = 60%
Concentration of salt in the mixed solution = 15%
The pure solution and the salt solution is mixed in the ratio of --> (60 - 15)/(15 - 0) = 3/1
1/x = 3/1
x = 1/3
Answer: B
