Answer:
The correct answer to the question is 2.7 Liters of water, that is;
to increase the concentration to 200 g/L, 2.7 L of water should be boiled off
Explanation:
To solve this we list out the known variables
We note the concentration of brine = 110 g/L
That is each liter of brine contains 110 g of solute
To increase the concentration to 200 g/L we have
6 liters of brine containing 6 L × 110 g/L = x L of 200 g or solute salt
to have 200 g
660 = 200 × x or x liters = 660/20 = 3.3 L
However to arrive at the concentration, then 6 L - 3.3 L must be boiled off thus 2.7 L must be boiled off to increase the concentration to 200 g/L.
