Question

2.9 5.85 g of NaCl are dissolved in 500 cm of water.
Calculate the formality of the solution.

Answer 1

Answer:

5.85 g NaCl when dissolved in 1000 cm^3 solution becomes (5.85)/(58.5) formal solution or 0.1 formal solution . 5.85 g NaCl when dissolved in 500 cm^3 solution becomes (2 X 0.1) or 0.2 formal solution .
