Answer :
The number of moles of the NaCl 1.20L of 2 M solution is 2.4. One mole is 58.5 g. Then the mass in grams of 2.4 moles is 140.4 grams. Thus, option D is correct.
The molarity of a solution is ratio of the number of moles in the solution to the volume of the solution in liters.
then,
number of moles = volume × molarity.
given,
molarity = 2 M
volume = 1.20 L.
number of moles = 2 M× 1.20 L = 2.4 moles.
mass of one mole of NaCl = 58.5 g
then mass of 2.4 moles = 140.4 grams

Answer: D) 140g
Explanation: no. of moles of NaCl = molarity X volume in litres = 2 X 1.2 = 2.4, and molar mass or mass of 1 mole of NaCl = 58.44 g, so 2.4 moles NaCl = 140.256 g
