1. Calculate the grams of Na2CO3 required to prepare 250.0 mL of 0.375 M Na2CO3 solution.
2. The reaction of sodium carbonate with hydrochloric acid produces carbonic acid and sodium chloride.
If 25.00 mL of O.0980M sodium carbonate is required to completely react with 17.12 mL of hydrochloric acid solution, what is the molarity of the hydrochloric acid solution?
3. A 80.1 mL sample of hydrogen is collected over water at 23°C and 725 torr from the reaction of magnesium and hydrochloric acid. The vapor pressure of water at 23°C is 21.0 torr. How many grams of hydrogen gas were collected?
