What is the molarity of a solution formed from 20.0 grams of NaCl dissolved in 650.0 mL of H2O?

Solution Preview

Molarity (M) is defined as moles per 1 liter (moles/L). To figure out the molarity of the solution, you need to determine the number of moles of NaCl in 20 grams. To determine the number of moles of NaCl, you need to know its molecular weight (MW), that is, how many grams are in ...

Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 28.71 mL of 0.1822 M standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 2.70 mL and the final reading was 30.33 mL. What was the molarity
