You dissolve 12.6352 g of potassium iodide in water and bring the volume of solution to 250.0 ml. What is the molar concentration of KI and what volume of 0.0436 molar hydrochloric acid is required to react with 30.0 ml of 0.0278 molar LiOH?
A quanity of oxygen gas was collected over water at 30 c in a 475 mL container. The pressure in the container was measured to be 105 kPa. How many grams of oxygen gas were collected?
Calculate the mass of AgNO3(s) that must be added to 0.500 L of a solution of 0.154 M NaClsolution to precipitate ‘all' of the chloride ion. The ‘all' means that we want to add the same number of moles of silver ion.
