A solution contains 8.88g of KBr in 500.0mL of solution and has an osmotic pressure of 6.97atm at 25 C. Calculate the van't Hoff factor (i) for KBr at this concentration.
When electrical current of unknown magnitude is run through the device for 3.50 min, 16.1 mL of water-saturated H_2(g) is collected. The temperature and pressure of the system are 25 degreesCelsius and 715 torr.
Imagine that you are trying to design a new battery using the elements tin (Sn) and a halogen (Cl2, Br2, or I2) and you are using the reactions when SnCl2 and KBr are combined.
