You add 21.3 mL of sulfuric acid to 35.0 mL of water. What is the percent concentration of the resulting solution? You want to make 1,000 g of a 35 ppm solution of ammonia. How many milligrams of ammonia should you use? You want to create 2.0 L of a 0.80 M stock solution of hydrochloric add. How many grams of hydrochloric acid must you use? You are writing up a lab report when you realize that some of your notes are missing. You know that you diluted a stock solution of hydrochloric acid to make 1.0 L of 0.50 M hydrochloric acid. You can't remember the concentration of the stock solution, but you know that you used 530 mL of said solution. What was the stock solution's concentration?
