Constant-boiling HCl can be used as a primary standard for acid-base titrations. A 50.0 mL sample of constant-boiling HCl with a concentration of 0.1166 M was collected and titrated to an end point with 37.17 mL of Ba(OH)2 solution. What is the molarity of the Ba(OH)2 solution?
Arrange the following aqueous solutions in order of increasing freezing points
A running automobile produces CO at a rate of 188g CO per hour. A car is left idling in a garage 5.2m long, 4.0m wide, and 2.2 m high at 20 degrees C. How long would it take to build up a lethal concentration of CO of 1000 ppmv?
