The transport number of lithium ion is 0.56 in LiBr solution at 25 degree Celsius. What is the transport number of bromide ion ? *
Physical Chemistry
A 22.5 mL sample of liquid ethanol (C₂H₅OH, density = 0.789 g/mL) was injected into a 10.0 L cylinder containing O₂ at a pressure of 4.50 atm and a temperature of 25°C. The cylinder was heated to 125°C and a spark was used to ignite the ethanol, which was completely combusted. What was the final total pressure in the cylinder (in atm) after the reaction, while it was still at 125°C?

Physical Chemistry
A sample of copper was analysed and found to contain two isotopes 63-copper and 66-copper. All the ions were accelerated and travelled through a flight tube.
63Cu+ ions took 1.4242 x 10^-5s.
How long would 66Cu+ ions take to travel along the same flight tube?
