In a science equation, a formula is usually used to determine the mass of something. In this case, a formula is used to determine the amount of grams there are in solid barium sulfate if you combined the thirty-five milliliters of 0.160 M of barium chloride with fifty-eight milliliters of .065 M of sodium sulfate.
When these two substances react together, they form of sodium chloride in a liquid form. It would be aqueous. Sodium chloride is a fancy word for table salt. It is represented by the chemical formula NaCl. It has a molar mass of 22.99. If you had one hundred grams of sodium chloride, you would have almost 40 grams of sodium and almost 61 grams of the chloride.
