Hello!

The right answer is C) 60 g/L

To know the final concentration of NaI solution, you'll need to calculate the initial amount of NaI in grams in the following way:

$2 L * \frac{0,2 moles NaI}{1L}* \frac{150 g NaI}{1 mol NaI}=60 g NaI$

Next, you only need to calculate the concentration on NaI in the new 1 L solution, because only water is evaporating from the initial solution:

$CNaI= \frac{60 g NaI}{1 L}=60 g/L$

Have a nice day!
