Problem

Children without access to clean drinking water are at risk of electrolyte loss. In response to this problem, a team of scientists is working to develop a rehydration solution with several key ingredients.
several packets containing salts, labeled with the ingredients, directions, and a picture of an orange to indicate the flavor.
Packets of oral rehydration salts (ORS) can be mixed with water to treat dehydration
They determine that each 150 mL serving will contain 0.66 grams of NaCl, which can replenish sodium ions essential for regulating nerve and muscle function. The molar mass of NaCl is 58.44 g/mol.
Calculate the concentration of NaCl in the solution in mol/L.
