Answer:

A. Convert the 200 mol of water to kilograms of water.

Explanation:

To find the molality of 10mol of NaCl in 200mol of water, convert the 200mol of water to kilograms of water.

Molality is one of the several ways of measuring concentration of a solute in a solvent;

 Molality  = [tex]\frac{number of moles of solute}{mass of solvent}[/tex]

  • To solve this problem, simply convert the 200mole to mass of water.
