Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter. Add sodium hydroxide to water— do not add water to solid sodium hydroxide. Be sure to use borosilicate glass (e.g., Pyrex) and consider immersing the container in a bucket of ice to keep the heat down.

We can use the rearranged molarity equation to calculate the moles of NaCl needed for the specified concentration and volume: mol NaCl = [ NaCl] × L of solution = 0.800 mol L × 0.250 L = 0.200 mol NaCl. We can then use the molecular weight of sodium chloride, 58.44 g mol , to convert from moles to grams of NaCl :

The following equation is used for calculating acid and base molarity where the concentration is given in wt %: [ (% × d) / MW] × 10 = Molarity. Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight). The above equation can then be used to calculate the Molarity of the 70 wt % Nitric Acid:

Molar mass is not to be mistaken with molecular weight - the mass of a single molecule of a substance, given in daltons (e.g., a single HO particle is 18 u). You may need the periodic table to calculate molar mass. Even though both of these variables are similar in value, they describe different things.
