Document Summary
A 100. 0 grams sample of kf is dissolved in water to make a 500. 0 ml solution. The density of the solution is 1. 160 g/ml. The vapor pressure of pure water is 23. 8 mmhg. 22. 4 mmhg: the abundance of silver in seawater is 0. 00522 mg/l. 3. 05 m: the amount of lead in tap water is 3. 20 ppb. The bath tub holds 125 liters of tap water. The density of the tap water (solution) is 1. 008 g/ml. Freezing point constant for water is kf = 23. 4: name two factors that can affect the rate of a reaction, use the following information to answer the questions: 2 co + o2 --> 2co 2 ; rate = k [co ]3 [o2]2 (a. ) ___________ (c. ) what are the units for the rate constant, k?__________: given the following balanced reaction: n2 + 3 cl2 ----> 2 ncl3. The initial amount of nitrogen was 5. 50 m. after 2. 5 minutes, the amount of nitrogen was 4. 05 m.
