Question

How many grams of sodium chloride are there in 55.00 Ml of a 1.90 M aqueous solution of sodium chloride? any idea.

2. What is the concentration of chloride ions in a 0.193 M solution of potassium chloride?..heeeeeeeeeeeelp.
1.
moles NaCl = M x L
grams NaCl = moles x molar mass.

2.
You have 1 mole Cl ions in 1 mole KCl; therefore, the concn of Cl ions in 0.193 M KCl must be 0.193 M.
