Some amount of water is evaporated from a 2.0 l, 0.2 m nai solution, to from a 1.0 l solution. the molar mass of nai is 150 g/mol. what is the final concentration of nai solution in? a. 30 g/l b. 15 g/l c. 60 g/l d. 45 g/l

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:



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:



Have a nice day!
